These are custom made for us and designed for low end torque, but also plenty of top end speed. I personally run this on my bike and it is truly a monster! Power wheelie at 45mph with a 5" extended swingarm. This will require our 200mm dropout swingarm. I am running 400 line amps and 1000 phase from a fardriver 721000 and have been for months. The motor is rated for 5000 watts, but like all QS they under rate them by a lot. I push 30,000 watts to mine with no issues! Any warranty would be handled directly through the manufacturer. It is recommended by them that you run 250/750. I hit 75 mph and let off, if anyone is braver than I, please keep us posted on your top speed records! It gets there fast. Recommended for only street use. I was always really impressed with the qs165 setup we offer, but this is on a whole other level.
