BlueSunshine Front and Back Disk Brake Kit - 160mm For 80cc Gas Motorized Bicycle - Freewheel Threaded Hubs Hole distance of 48mm

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

just like the other reviewers i shoulda listen to... so here i m all these packages unpacked, tools scattered about, just got back from having a mechanic break loose the 2 bolts on the 2 of the rotors cuze they were torqued on so tight .... and they're the WRONG bolt hole pattern..! I realize they prob don't speak english ~ but dont they speak the SAME language so they can match bolt hole patterns...? OBVIOUSLY not or maybe the bolts would line up... but why advertise the (supposedly) mateing parts on the same page if the don't go together? Whatever - gonna spend the rest of the evening repackaging to return, cleaning up my workspace and putting aside the 1/2 finished conversion to mag wheels an disk brakes on my motorized bike and wait and RE-research who might have the right sizes ~ THAT match ~ then reorder and reassemble the mess that WAS my motorized transport. These disk brakes do NOT directly bolt onto the 10 spoke "star" pattern "motorized bike mag wheel" assemblies as claimed. Someone should be sued for false advertising and wastiing alot of peoples time. they probably won't even post this ~ although ive spent 100's of dollars on amazon ~ this is my 1st review and im extremely unhappy...! i got better things to do than write negative reviews and having to file law suits. save yourself the headache ~ im not sure yet what the correct path i'll have to choose to get A to fit to B to fit to C but its not rocket science.... although makes me wonder who theyve got in their R&D dept... obviously nobody that gives a &(^%.... good luck ~ measure twice / cut once ~ someone needs to go back to school

Buen kit de freno

I used the caliper since my front fork didnt hold the size of my new rotors. Way better than v band brakes.
