Lots of Torque. Paired with a RM85 radiator. Water temps rarely get above 165. Hits 50mph with ease. I've had it up to 57mph. My only complaint is the size of the lower spigot. Eats belts for lunch.

I bought it for my urban express. The kit runs great, never had a more consistent power band, and it's significantly quieter than my DR ever was, but I spent the first 3 days fighting leaks. The head gasket has no O-ring, so you have to have all the head bolts torqued perfectly, otherwise it will slowly leak into the combustion chamber, causing your plug to foul every time it sits. Another issue I had was that coolant kept exiting out of my head bolts, I fixed this by adding 4 O-rings. I am running a small 50cc dirtbike radiator and temps stay between 170 and 200 when I'm cruising at 40+ mph on my gravel road path. I bet the Polini radiator listed would cool it perfectly. Everything else is great on the kit, I expect it to run forever from now on, Liquid cooling for the win! TLDR: kit is fine, but can be finicky for leaks because there is no o-ring on the head gasket. Buy it for a challenge and some long range crusin'!
Lots of fun.
