I just got the new razor rsf650 delivered today from Amazon. One of my neighbors has a mx500 that he bought for his kids. He let me ride it and I knew I had to have one. Then after searching on YouTube I came across this bike. I think it was released a couple months ago. Same electronics as the mx650. 10" cast aluminum wheels with 100/80-10 tires, Tall adjustable rear shock with a ton of travel. Batteries sit low in the frame on this model, and I like the battery/engine cover way more than the mx bikes. Neat little hidden compartment in the tank.Bummer there's no front suspension though. Going to be overvaluing this to 48v with a new controller and keyed throttle. Plus I'd like to see if I can get an mx front fork to work.

Made a battery hold down for the extra battery configuration out of steel strap with some thin cork for separation and protection. Also a little mounting plate welded on for the new controller. Got everything hooked up and bench tested this afternoon. Only problem I had was the stock on/off switch didn't like the extra voltage so it died. I had to bypass it, but no matter because the throttle has a keyed switch anyway.

Slick, doing a great job, compared to a PR200 Razor 250w, 650w on 48v is like 150% more power & torque. I sold most of the PR200 parts and kept the frame to make a chopper and put Cateye front forks and turning it to gas, still a lot of work left to do on the frame.

Luckily no. just the charger. no biggie, ordered another for $28. trying to re-configure the chain tensioner now. stock tensioner has the chain ride against 2- steel bearings. its super loud. need to find a super small plastic wheel to replace those bearings. should quiet it down quite a bit.

Yeah, what's up with bike?? Way back, I bought a PR200, 250w for my 10 year old son, first thing he said is it too slow, lol.
I owned a NHRA 1015cc Pro Stock drag bike, after going 160mph in the 1/4 mile, I could not take it, lol.
I bought a QC-50 shocked mini dirt bike front fork about $60 total, it's really a Pogo stick, planning to put it on my Lucky 7 custom bike. As long as the triple clamp bolt fits through the neck bearings you can adjust it to fit.
