19" front and 17" rear spoked TUBELESS wheel kit to fit HONDA GB350S

With the introduction of our new black powder coat SMPRO TUBELESS spoked wheels, we are now able to offer the same convenience with regard to puncture repair as you have with your standard cast aluminium wheels, but in a far more robust and repairable/rebuildable spoked wheel combination. 

Built around the SMPRO aluminium rims together with our own in-house design and manufactured hubs which accept all the OEM cush-drive, brake disc and ABS hardware, these premium-quality wheels will enhance both the all-terrain performance and the style of your GB350S.

Each custom-built wheel kit consists of:

Front wheel: 19” diameter x 2.50 wide, 36 spoke, SMPro aluminium rim, laced with heavy-duty stainless-steel spokes and nickel-plated brass nipples onto our own CNC machined billet aluminium front hub. The front wheel also comes with our own laser-cut disc carrier, to mount the OEM disc, and a new ABS ring. Also included is a high-quality plastic moulded front fender, and associated mounting hardware to suit the larger 19” front wheel.

Rear wheel: 17” diameter x 3.50 wide, 36 spoke, SMPro aluminium rim, laced with heavy-duty stainless-steel spokes and nickel-plated brass nipples onto our own CNC machined billet aluminium rear hub - specifically designed to accept the OEM cush-drive assembly, and brake disc/ABS sensor components.

Both front and rear hubs are manufactured from 6082T6 billet aluminium alloy, and black Xylan coated, for a durable finish.

SMPro rims are a high-quality extruded aluminium rim and come powder-coated in classic Gloss Black for durability and ease of touching in any scratches if they ever occur.

Another benefit of the CWC Airtight System process, is that in the event of a puncture that could not be repaired by normal tubeless repair, then the tubeless valve can be removed from the rim, then a normal inner tube fitted in order to carry on riding, until a more permanent repair can be completed.

Heavy-duty "Bulldog" stainless steel spokes have 60% greater tensile strength than typical OEM specification mild-steel spokes, and benefit from inherent corrosion resistance. 

Our spoked wheels are supplied ready to fit with new bearings and seals and accept all the OEM hardware to mount the rear sprocket cush-drive assembly, brake disc rotors and ABS sensor components. All you need is your own choice of tyres & tubes.

Rim tapes are included with each wheel.

Our rim sizes (19" x 2.50 front and 17" x 3.50 rear) were chosen specifically to enhance the off-road performance and all-round ability of the GB350S and allow a wide range of all-terrain 50/50 style tread pattern tyres to be fitted from any number of manufacturers. 

For the GB350S used in mixed terrain on and off-road riding scenarios, we would suggest you fit a 110/80 x 19" front size and 140/80 x 17" rear size tyre - and our recommended brand/model would be the Continental TKC70 or TKC70 ROCKS in these sizes, which over the years and during many thousands of miles of mixed terrain riding, we've found work particularly well both on and off-road on the GB350S

FITTING INSTRUCTIONS

Benefits of our wheel kit

• Rear hub is designed to work with the OEM cush drive and rubbers.
• Our rear hub/rim is 36 spoke pattern, much stronger and resistant to flex.
• Hubs supplied with bearings & seals.
• Both front & rear hubs designed to work with OEM discs, rear ABS ring and OEM screws.
• High-tensile "Bulldog" spokes are 33% larger cross section, and consequently 60% stronger tensile strength than the OEM plated mild steel spokes, plus they are corrosion-proof.
• Nipples are nickel-plated brass, again, corrosion-proof, maintenance free.

Both rims are high-grade aluminium alloy.

The rim sizes are 19"x 2.50 front and 17"x 3.50 rear, 36 spoke hole pattern.

IT IS NOT POSSIBLE TO FIT THE OEM REAR TYRE 160/60-17 AS OUR REAR RIM IS SLIGHTLY NARROWER THAN OEM CAST WHEEL RIM. OUR RECOMMENDATION IS A 140/80-17 REAR TYRE, OR ALTERNATIVELY THE POPULAR 150/70-17 PROFILE SIZE - TYPICALLY AVAILABLE FROM ALL MAJOR TYRE MANUFACTURERS. 

DO NOT USE ACID, OR ALKALI-BASED WHEEL CLEANERS TO REMOVE DIRT AND BRAKE DUST, AS THESE CAN CORRODE AND REMOVE THE POWDER-COATING AND TARNISH THE STAINLESS-STEEL AND NICKEL-PLATED BRASS NIPPLES. USE A PH-NEUTRAL CLEANER, OR SOAP AND WATER.
