Razor MX500 & MX650 6-Pin Throttle and Controller Kit

Works fine. Great price for both controller and accelerator. Thank you

Awesome. Almost plug and play for razor dirt bike. Just swap battery plugs and guess the brake safety plug. Goes 21 mph on gps ! Double the speed !! Also got a big battery.

Fit my 2010 version 3 razor MB650 dirt rocket. Since my bike was older I had to purchase a new hand throttle and the control module. Easy to assemble and worked like a charm. I had to call razor for a mounting bracket because the new control module bolt holes don't line up. They sent it 2 day air at no which was kind of them. I must say Razor corporation that produces these electric bikes are customer oriented. It's a breath of fresh air.

Some of the clips were warped but I ultimately managed to make it work. I'm sure the clips being warped was not common and accidental but I had to take away one star because of that.

So this is simple. The bike stopped working. I checked the wiring and after replacing a blown fuse the bike still didn’t work. Since this was such a good price I bought this instead of just the throttle, which I thought was bad. I disassembled the bike and first tried the new throttle, still no good then tried the new cpu and the bike worked. I then tried the old throttle since it was still on the bike and would save me work and the bike worked so I only have to replace the cpu and then button the bike back up. My some road the bike until the battery died and not fire balls. My guess is if you get a fire ball you messed something up while doing this, but I find it had to do that.
