I remember I went to an AHRMA race and they have a class called Formula Lightning and it's an all electric class and I talked to this guy that had oil cooled his Zero SR motor. I wish I got a better picture of it. He must have machined some kind of jacket to fit over the motor and pumped oil...

There are 2 situations where I can overheat a motor repeated hillclimbs and supermoto racing. Hillclimbs because you are putting a lot of load and not going that fast. Lugging the motor causes it to overheat and holding the throttle wide open then slowing down and speeding back up again. At...

Oh ok watercooling for the controller. I'm more interested in watercooling the motor. I have been able to overheat the QS138 at a supermoto race. The EBMX X-9000 I have NEVER overheated. I think 120F is the most I've gotten it. The QS though will regularly hit 200F when ridden hard. I wish...

Cool is this watercooled?

Was looking through some pictures and saw some pictures of some Alta Redshifts that raced during a Supermoto USA race at Sonoma Raceway in 2019 and thought I should share em. That's the first time I had seen a supermoto Redshift and was excited. Who'd have thought I would be racing one today...

I always just unplug the headlight if I am at the track. I've been meaning to install a headlight on off switch, I would tap it into the ground and use the switch to break the connection. I was also thinking about installing a switch like this has a H4 plugs so you wouldn't need to cut any...

Thanks for watching. Yeah the Aprilia is a pretty cool bike. It was there so people could race it in the bigger bikes class. The owner is trying to sell it, they intended to use it as a trackday bike but like you mention its not very good at really tight tracks.

Asphalt Practice - This is a compilation of all the practice I did on the Redshift and Light Bee on the asphalt course. This course was really short and more suited to minis and included a jump! It reminded me of the Treasure Island TT.
