BlueSunshine Front and Back Disk Brake Kit for 80cc Gas Motorized Bicycle, 160mm

The brakes were a bolt on for our MX650 with out the extra ring on the discs. The brake handles are garbage. The left one broke in my 12 year old sons hand on the second ride. He did not crash, he did not fall over, but when he pulled on the brakes, the silver pull snapped.

This is an awesome deal for the price. Some of our customers are pleased to get good quality / economical brake kits rather than more expensive options.

I sent them back to the seller. Didn't fit my rims,junk. Looked just as described in the literature. Came before a couple of other things in that order.

These are commonly recommended by razor mx500 owners. Bolt pattern for the rotor matches. You take the adapter off the rotor. Bolts right up. Caliper requires proper spacing. Front cable is long and needs some trimming. Better than to short. I do since thebfront had a bit more pressure for my application, but I'm pleased overall. Nice little kit for the price. Will be upgrading to some sort of hydraulic setup using these rotors soon. I did notice most users failed to ensure the bolt pattern was correct prior to purchase. Does seem to be odd, and not sure what else they would even fit.

It was a heck of a time getting the adapter off i had to shave the bolt heads down. Only to find that i need a diffrent/ smaller bolt separation i got the 44cm but i need the 42cm. Not the sellers fault, so when i get a chance im going to get the size i need from this same seller
