Warp 9 17" Supermoto Wheel Set

The Warp 9 17" Supermoto Wheel Set is the ultimate street and asphalt performance transformation for the Sur-Ron platform. Engineered by Warp 9 Racing in Salt Lake City, Utah, this complete front and rear wheel package converts your knobby-tired off-road bike into a razor-sharp canyon carving supermoto machine with unmatched road grip, agile turn-in, and aggressive styling.

The kit features 17x2.15" front and 17x2.50" rear rims extruded from heavy-duty 7000-series aerospace aluminum alloy, laced with heavy-gauge stainless steel spokes and nickel-plated nipples to CNC-machined 6061-T6 billet aluminum hubs. High-grade sealed cartridge bearings and precision wheel spacers ensure silky-smooth rotation and long-lasting protection against water and road grime.

Dynamics of 17-Inch Wheels: Reducing wheel diameter from stock 19-inch wheels to 17 inches lowers the bike's center of gravity by approximately 1.5 inches and significantly reduces rotational gyroscopic inertia. This allows the rider to flick the bike into tight corners effortlessly, hold precise lean angles, and accelerate out of turns with confidence. Furthermore, the 17-inch diameter unlocks access to high-grip motorcycle street, rain, and track compound tires.

Installation & Axle Torquing: Wheels arrive pre-laced, professionally trued, and ready to install. Verify drive chain alignment and torque front axle pinch bolts to 10–12 Nm and rear axle nuts to 40–45 Nm, verifying that wheel spacers are seated squarely against inner bearing races.

Spoke Maintenance & Break-In: Inspect spoke tension across both wheels after the initial break-in period of 100 miles using a spoke wrench, tapping each spoke to check for a uniform acoustic pitch.

Frequently Asked Questions:

Q: How does switching to 17-inch supermoto wheels change the bike's handling? A: It lowers the center of gravity and reduces gyroscopic inertia, allowing for much quicker steering turn-in, aggressive lean angles, and access to sticky street motorcycle tires.

Q: Do these wheels come pre-assembled with bearings and spacers? A: Yes. Warp 9 wheel sets arrive fully laced, trued, and equipped with sealed bearings, inner crush tubes, and precision wheel spacers.

Q: What tire sizes fit on these 17-inch supermoto rims? A: Standard street tire sizes include 70/90-17 or 80/90-17 for the front (17x2.15 rim) and 90/80-17 or 100/80-17 for the rear (17x2.50 rim).

Q: What material is used for the rims and hubs? A: The rims are extruded from 7000-series alloy and the hubs are CNC-machined from 6061-T6 billet aluminum with stainless steel spokes.

Q: Do I need to modify my swingarm to fit the 17-inch rear wheel? A: No. The 17x2.50 rear wheel is engineered to fit within stock swingarm clearances with standard street tire profiles.

Spoke Maintenance & Axle Torquing: After the initial break-in period of 100 miles, inspect spoke tension across both wheels using a spoke wrench, tapping each spoke to check for a uniform acoustic pitch. Always torque front axle pinch bolts to 10–12 Nm and rear axle nuts to 40–45 Nm, verifying that wheel spacers are seated squarely against inner bearing races to prevent binding.

CNC Hub Tolerances & Bearing Longevity: Warp 9 hubs are machined with bearing bore tolerances within 0.005mm, ensuring inner bearing races remain perfectly concentric. Double-lip rubber contact seals keep out water and road salt during all-weather street commuting, extending hub bearing life.
