Description
Embracing the philosophy that serious riding demands meticulous engineering, we’ve gone the extra mile to find a wheel that rises to the challenge. Our quest led us to SM Pro Wheels.
As one of the premier suppliers of motorbikes wheels, SM Pro stands as the wheel wizards, crafting sets for the elite: KTM, Husky, Honda, Yamaha, Kawasaki, Suzuki, GasGas… Legit? It’s not just a claim; it’s a swaggering testament to their legitimacy!
The Sur Ron Ultra Bee comes standard with a set of 19″ wheels, perhaps for economic or weight-related reasons. However, it’s evident that the bike is not made for this wheel size. Upon receiving his bike, Cyprien wasted no time (well, maybe a few kilometers) before swapping out the 19″ set for a proper 21/18″ one.
Compared to 19″ wheels, 21″ wheels boast significantly lower rolling resistance, making obstacles appear relatively smaller and remarkably easy to overcome. This makes the 21″ wheel our preferred choice for enduro riding, as it helps reduce rider fatigue on challenging terrain, enhances the bike’s stability and positions our light electric bikes on par with their petrol-powered counterparts.
If you’re contemplating a single upgrade for your Ultra Bee, the 21″ wheel should be it, propelling the Ultra Bee into its rightful place: the full MX-sized world.
The 21″ front wheel has long been the standard size for dirt bikes, and for good reason. It not only provides unparalleled stability at high speeds but also takes your ability to navigate obstacles to new heights, making it the ultimate enduro weapon.
This high-end wheel is meticulously handcrafted in the UK using premium components. The rim boasts aviation-grade 7050-T6 aluminum, while the hub is CNC machined from billet aluminum and comes equipped with SKF bearings, seals, and spacers. Complementing these features are the robust 10-gauge spokes crafted from high-tensile, heat-treated steel, and the durable nickel nipples, ready to withstand the toughest rides.
Enter the 21″ wheel! Here’s what it can do for you:
- Enhance roll-over ability
- Mitigate arm-pump on challenging terrain
- Assist in clearing obstacles like rocks and logs
- Improve comfort on steep descents
- Provide excellent stability on challenging terrain and at higher speeds
- Offer the broadest range of tire options as the most widespread wheel size.
