Ultra Bee V2 Rear Brake Kit for Pit Bikes
Massive stopping power for the rear of your bike. This kit swaps your undersized stock rear brake for a Surron Ultra Bee V2 caliper and master cylinder setup, a huge braking upgrade for riders who've outgrown what came on the bike. If you've ever ridden your rear brake down a steep hill or into a corner and felt it fade, go soft, or just plain not stop you, this is the fix.
