Wow!!! Been gradually modifying a Razor RSF650 and decided to give this motor a try when finally going brushless. I have to say it has far exceeded my expectation. For the price its impossible to go wrong but I'm pushing almost 17kw peak at 75v 220 amps. Unbelievable to say the least. Highest temperature I've measured is 105F after over an hour run time (low autumn temperatures, would be higher in hot summer). Reaches a top speed of 41.4mph with 1:7.3 gear ratio and 10 inch rims. Easily pulls wheelies and effortlessly burns rubber. With controller in boost mode you really do have to lean over the bars to hold the wheel down and hang on tight. Had to wire an economy switch to my controller to prevent flipping over backwards unexpectedly when accelerating out of tight turns.Very glad I didn't go for a more expensive motor because this one is taking max power from my controller without breaking a sweat. Have been running it for over a month using it daily with no degradation so far. Only down side is it ruined my stock chain within a week!! Stretched it beyond use. I suppose that's a good problem to have though.
