A Complete Royal Enfield Hunter 350 Scrambler Conversion
This 2024 Royal Enfield Hunter 350 was developed as a complete scrambler build rather than a motorcycle fitted with a few unrelated styling accessories.
The objective was to change the proportions of the entire bike: a straighter seat line, a shorter rear end, a taller front profile, a cleaner cockpit and a stronger visual connection between the fuel tank, side covers and wheels.
Most of the transformation uses model-specific Bonvent components designed around the original Hunter 350 mounting points and electrical connectors. The rear conversion, flat seat, side covers, mudguards, lighting and speedometer relocation can therefore be installed without cutting the frame or splicing the factory wiring.
The motorcycle also includes several project-specific modifications: custom tank paint, a 900 mm tracker-style handlebar, Shinko adventure tyres and a bespoke high-mount exhaust. These elements complete the build, but they should be distinguished from the plug-and-play Bonvent accessory system.
Riders planning a similar project can explore the full range of Royal Enfield Hunter 350 custom parts.
Correcting the Original Hunter 350 Proportions
The standard Hunter 350 has a compact and approachable roadster shape, but several original components create descending or rounded lines around the centre and rear of the motorcycle.
The original seat has a relatively bulky profile. The factory side covers also slope downward toward the rear, making the centre of the bike feel lower and more enclosed.
For this scrambler conversion, the main design objective was to create a straighter horizontal line running from the fuel tank to the rear of the motorcycle. The new seat, raised side covers and shorter mudguard all contribute to this more classic proportion.
The result brings the Hunter closer to the visual language of vintage scramblers and trackers while retaining its original frame and accessible road-bike character.
A Short Rear Mudguard With Integrated Splash Control
The rear transformation uses the Bonvent Hunter 350 Rear Mudguard Kit.
Short rear mudguards often create a practical problem. When a large gap remains between the end of the mudguard and the top of the license plate, water and road debris can travel directly through that opening toward the rider’s back.
The Bonvent system uses a dedicated anti-splash return above the license plate area. This closes much of the open path between the mudguard and the plate, helping reduce the spray normally associated with an extremely short rear fender.
It allows the rear mudguard to remain visually compact without treating splash protection as an afterthought.
Integrated mini LED tail light
A compact LED tail and brake light is integrated directly into the rear mudguard assembly. The smaller lighting unit removes the visual bulk of the original rear light while keeping the essential rear lighting functions in a clearly visible position.
The light used in the kit is E-mark / CE specified. Final positioning, plate visibility and road-use compliance should still be checked according to the regulations of the rider’s country.
Frame-mounted license plate support
The license plate support passes discreetly beneath the mudguard and attaches to the motorcycle’s structure rather than relying on a fragile decorative extension.
Its mounting area is designed to work with a broad range of international plate dimensions. Because number plate sizes and fixing positions vary worldwide, the final installation should always be checked against the actual plate and local requirements.
Rear indicator mounting points are positioned on each side of the plate, creating a symmetrical lighting arrangement without adding unnecessary hardware around the tail light.
A Flat Seat Conversion Without an Empty Gap Underneath
The Bonvent Hunter 350 Flat Seat replaces the rounded original saddle with a cleaner and more horizontal scrambler-style profile.
Simply placing a conventional flat seat on a Hunter 350 often leaves a visible empty space between the seat base and the original frame. This can make the conversion look unfinished, even when the upholstery itself is attractive.
The Bonvent solution integrates tubular frame-style panels beneath the seat. These elements visually extend the motorcycle’s structure and give the impression of a more traditional exposed-frame motorcycle without modifying the real frame.
Additional compact under-seat side panels close the remaining gaps. They are held in position by a dedicated metal bracket beneath the frame, producing a more seamless transition between the seat, side covers and rear mudguard.
The complete assembly uses the original motorcycle mounting structure. No frame cutting, welding or permanent drilling is required.
A straighter and more supportive seat profile
The upholstery uses padded ribs rather than a thin decorative cover. This maintains the visual rhythm expected from a vintage scrambler seat while providing a more substantial riding surface.
The seat line remains close to the original Hunter 350 height but feels visually narrower and cleaner. This helps preserve the accessible nature of the motorcycle while changing its overall identity.
Raised Custom Side Covers With Vented Grilles
The build uses the Bonvent Custom Side Covers for Hunter 350.
Compared with the original triangular side panels, the Bonvent side covers have a rounder shape and a slightly raised rear line. This removes the downward-looking profile of the factory panels and creates a more balanced transition toward the flat seat.
Five elongated openings and internal mesh add depth to the panels. The vent pattern introduces a mechanical detail that works naturally with scrambler, café racer and flat tracker styling.
The side covers use the original Hunter 350 mounting points. They can be installed without cutting, drilling or permanently altering the frame.
Used together with the tubular frame-style seat panels, they make the centre of the motorcycle feel more structured and considerably less bulky than the standard configuration.
High and Low Front Mudguards Used Together
The front-end conversion combines two different Bonvent components:
The high-mounted section creates the unmistakable scrambler front profile. Its position above the tyre visually raises the front of the motorcycle and connects it with the wider handlebar and block-pattern tyre.
The lower short mudguard remains close to the wheel. It provides a practical fender section above the tyre while keeping a much lighter appearance than the original full-size mudguard.
Using both components creates a more complete front-end solution than fitting a decorative upper mudguard alone. The upper part establishes the scrambler identity, while the lower part continues to provide useful coverage.
The lower mudguard uses an adjustable metal bracket that allows its position to be adapted to the tyre setup. This is particularly relevant here because the build uses a wider 120/70-17 front tyre.
A Compact 5.75-Inch LED Headlight
The original headlight assembly was replaced with the Bonvent Mini LED Headlight Kit for Hunter 350.
The compact 5.75-inch LED unit significantly reduces the visual mass at the front of the motorcycle. It creates more open space around the fork and makes the wide handlebar feel integrated rather than oversized.
The kit uses an adjustable mounting bracket developed for the Hunter 350. The smaller headlight remains centred between the fork legs and gives the front end a cleaner, more symmetrical appearance.
The LED headlight is E-mark specified and designed as a model-specific conversion rather than a universal light attached with improvised brackets.
Closing the gap left by the original headlight assembly
Removing the original Hunter 350 headlight brackets leaves a visible open area between the fork legs. Without an additional finishing component, that space can expose wiring and make the conversion look incomplete.
The Bonvent Front Fork Cover Plate closes this opening. Its powder-coated steel construction follows the fork area and creates a clean visual background behind the new headlight.
This small part is important because it turns the front-end conversion into a finished assembly rather than simply replacing the lamp.
Relocating the Original Hunter 350 Speedometer
The standard Hunter 350 speedometer is positioned asymmetrically in front of the handlebar. That offset arrangement works on the original roadster, but it becomes visually dominant once the headlight and surrounding components are reduced.
The Bonvent Speedometer Relocation Bracket and Extension Cable moves the original instrument to a centred position behind the handlebar, closer to the fuel tank and directly within the rider’s line of sight.
The original Royal Enfield display and its factory functions remain in use. Only its location changes.
A dedicated plug-and-play extension cable adds the necessary wiring length without cutting or extending the factory harness manually. Original-style connectors keep the modification cleaner and easier to reverse or diagnose later.
Combined with the smaller headlight, the relocated speedometer removes much of the visual clutter from the front of the motorcycle.
Compact Neo Scrambler Indicators and Dedicated Mounts
The original indicators were replaced with Bonvent Neo Scrambler LED Indicators.
Their compact shape works with the modern side of the Hunter 350 while remaining discreet enough for a minimalist scrambler front end. The indicators are E-mark specified and sold as a matched pair.
At the front, the Hunter 350 Front Indicator Mounting Brackets provide stable mounting points beneath the fork area.
The electrical connection uses the Hunter 350 Indicator Wiring Adapter Kit. Each adapter connects an aftermarket indicator to the original Royal Enfield connector without cutting or soldering the motorcycle wiring.
At the rear, the Royal Enfield Rear Wiring Adapter provides dedicated connections for the tail light, brake light, license plate light and rear turn signals.
Hard Tank Knee Pads That Visually Widen the Fuel Tank
The build also uses the Bonvent Tank Knee Pads for Hunter 350.
These are not generic soft rubber stickers. They are shaped from reinforced composite material and finished in matte black to match the other body components.
The Hunter 350 fuel tank is relatively narrow. The hard knee pads add visual width and structure to its lower section, helping the tank feel better proportioned against the wide handlebar, flat seat and larger tyres.
They attach without drilling or permanent tank modification.
PARTS USED

Explore the model-specific Bonvent parts used to create this motorcycle.
A 900 mm Tracker-Style Handlebar
A bespoke 900 mm-wide tracker-style handlebar was created for the project.
Its width changes the proportions of the motorcycle immediately. The Hunter feels broader from the front, while the rider’s arms are positioned further apart in a more upright and commanding posture.
The handlebar also helps connect the visual width of the front tyre, fuel tank and rear section. It gives the relatively compact 350 platform a stronger presence without adding unnecessary bodywork.
This is one of the project-specific modifications rather than a standard bolt-on Bonvent accessory. Any substantial handlebar change requires careful verification of throttle cable, clutch cable, brake hose, electrical wiring and steering-lock clearance before riding.
A High-Mount Scrambler Exhaust for the Hunter 350
The motorcycle uses a bespoke high-mount scrambler exhaust developed specifically for this build.
Traditional high exhaust systems can place the hot pipe directly beside the rider’s leg. On this project, the functional exhaust route drops beneath the side-cover area and follows the frame closely before rising toward the rear silencers.
Protective panels visually continue the upper exhaust line while helping separate the rider’s leg from the hottest part of the system. From the side, the exhaust appears to run directly through the upper section of the motorcycle, but the hotter functional route remains positioned lower and further inward.
A second visual tube at the front creates the impression of a twin-header layout and gives the single-cylinder Hunter 350 a more substantial mechanical presence.
At the rear, the system terminates in two functioning silencers. Their compact stacked layout supports the scrambler profile and gives the small 350 engine a deeper and more mature exhaust character.
This exhaust is a project-specific component and should not be presented as part of the plug-and-play product range unless a production version is made available.
Shinko Adventure-Trail Tyres on 17-Inch Wheels
The build retains the original 17-inch wheel format but uses substantially more aggressive Shinko adventure-trail block-pattern tyres.
The fitted dimensions are:
- Front: 120/70-17
- Rear: 140/80-17
The 120 mm front tyre fills the space beneath the combined high and low mudguard setup. At the rear, the taller 140/80-17 profile gives the motorcycle a more substantial stance and visually balances the shortened rear mudguard.
The large tread blocks are central to the scrambler identity of the build, but these dimensions differ from the standard road-oriented setup. Rim compatibility, tyre clearance, steering movement, mudguard clearance, load rating and local road-use requirements must be checked before reproducing the same configuration.
Custom Black Tank Paint With Graphics Beneath the Clear Coat
The fuel tank was refinished in black with Royal Enfield graphics sealed beneath the clear coat.
The simpler tank treatment removes visual noise and allows the silhouette of the motorcycle to become the main focus. Gloss black paint connects the tank with the mudguards and side covers, while the matte knee pads introduce a subtle contrast in texture.
Because the graphics are positioned beneath the final clear layer, the surface feels more integrated than an externally applied sticker.
The black tank also provides a neutral centre for the mechanical details around the engine, high exhaust, wide handlebar and block-pattern tyres.
What Is Plug & Play and What Is Bespoke?
It is important to describe the build accurately.
The model-specific Bonvent conversion includes:
- Flat seat and under-seat finishing panels
- Short rear mudguard and integrated lighting assembly
- Under-fender license plate support and anti-splash return
- Custom side covers
- High and low front mudguards
- 5.75-inch LED headlight and fork cover plate
- Speedometer relocation bracket and extension cable
- Tank knee pads
- Indicator mounting brackets
- Plug-and-play indicator and rear-light wiring adapters
These parts are designed around the Hunter 350 and use its original mounting points or electrical connectors where specified.
The following elements are bespoke additions to this particular project:
- Custom black tank paint
- 900 mm tracker-style handlebar
- High-mount twin-silencer exhaust
- Shinko tyre conversion
This distinction keeps the article technically honest. The Bonvent accessory conversion is designed to remain clean and reversible, while the bespoke components demonstrate how much further the platform can be developed in a complete workshop build.
French-Designed Hunter 350 Custom Parts
Bonvent Motorbikes is a French brand that develops its own custom motorcycle parts for Royal Enfield and Triumph platforms.
The objective is not to assemble a motorcycle from loosely matched universal accessories. Each Bonvent component is developed around the proportions, fixing points and practical constraints of the motorcycle for which it is intended.
Reinforced composite body parts, powder-coated metal brackets, dedicated wiring adapters and carefully finished upholstery all contribute to a more coherent result.
The parts are produced in small series and shipped from France to riders worldwide.
Final Result
This 2024 Royal Enfield Hunter 350 scrambler build demonstrates how a relatively compact roadster can be given a much stronger identity through coordinated changes.
The flat seat and raised side covers establish a cleaner horizontal line. The anti-splash short rear mudguard reduces visual weight while retaining practical protection. The high and low front mudguards, smaller headlight and centred speedometer completely reshape the cockpit and front profile.
The wide handlebar, high-mount exhaust, black tank and block-pattern tyres then take the motorcycle beyond a simple accessory installation and turn it into a complete custom project.
Most importantly, the visual transformation does not depend on cutting the frame or improvising electrical connections. The model-specific Bonvent components remain clean, removable and understandable for the rider who may need to service or return the motorcycle to its original configuration later.
