Key Features & Benefits (Bulleted List for Scannability)

Complete Bolt-On Assembly: Ships fully laced, trued, and ready to ride. Includes a high-quality rim, heavy-duty spokes, premium hub, integrated brake disc, and matching rear sprocket. Just transfer your tire, tube (or install a Tubliss/mousse), and bolt it on.
Optimized 18″ Diameter & 2.50″ Width: The 18″ diameter is the performance standard for off-road, providing a better tire profile, improved shock absorption, and reduced pinch flats. The 2.50″ inner width perfectly supports modern intermediate-to-hard terrain tires for a larger contact patch and enhanced traction.
Superior Strength-to-Weight Ratio: Constructed with a CNC-machined, high-grade aluminum alloy rim and precision hub. It’s stronger and often lighter than the stock wheel, reducing unsprung weight for more responsive suspension action and quicker acceleration.
Direct Fit & Hub Compatibility: Features the exact same 48-tooth sprocket mounting pattern and 203mm brake disc as the OEM Ultra Bee hub. Maintains perfect chain alignment and bolt-on compatibility with your stock brake caliper and axle.
Unlock Premium Tire Options: Opens up the vast, performance-driven world of 18″ motocross and enduro tires from brands like Michelin, Dunlop, Pirelli, and MotoZ. Find the perfect tread for your terrain.

Aggressive riders who bend rims and need a more durable, resilient wheel assembly.

Why Upgrade from the Stock 17″ Wheel?

The stock Ultra Bee comes with a 17″ rear wheel. Stepping up to an 18″ wheel offers tangible benefits:

More Tire Cushion: Taller sidewall absorbs impacts better, protecting the rim and improving ride comfort over chop.
Reduced Pinch Flats: More air volume and sidewall flex decrease the chance of pinching the tube on square-edged hits.
Industry-Standard Sizing: The 18″ size is dominant in dirt bike and enduro, giving you access to the best, most readily available tire models and compounds.

FAQ Section

Q: Is this really a direct bolt-on? No modifications needed?
A: Yes! This assembly uses the same hub spacing, sprocket offset, and brake disc as your stock Ultra Bee wheel. Simply remove your old wheel and install this one. You will need to adjust your chain tension.

Q: Will my stock Ultra Bee tire fit on this new wheel?
A: No. The stock Ultra Bee uses a 17″ tire. This assembly requires an 18″ motorcycle tire. This is a feature, not a limitation—it’s your gateway to superior tire performance.

Q: Does it come with a tire and tube?
A: No. This is a wheel assembly only (rim, hub, spokes, disc, sprocket). You must purchase an 18″ Motorcycle Tire and a standard 18″ Motorcycle Tube (or a Tubliss system) separately. We offer these on our site!

Q: Is the sprocket and brake disc included?
A: Absolutely. A 48T sprocket and a 203mm brake rotor are pre-installed, so you don’t need to transfer your old ones.

Q: Will this affect my speedometer or odometer?
A: Potentially, yes. An 18″ wheel with a similarly sized tire may have a slightly different overall diameter than the stock 17″ setup. This can cause a minor variance in speedometer reading. For precise measurement, a GPS speedo is recommended.
