I got a chance to ride the Kramer HKR EVO2 R motorcycle at Chuckwalla Valley Raceway thanks to a friend that owns one.
The Kramer is a really cool supermono that is made by a small manufacture in pretty small quantities. It has a KTM LC4 690cc motor puting out about 80hp. The motor is fuel injected and has some work done to the head so it puts out more power than the stock LC4. The ECU can be mapped using a laptop and you can adjust the throttle response and engine braking.
The bike has a trellis frame and composite bodywork and only weighs about 275lbs. It is super light and a lot of fun to ride.
Specs on the bike can be found on Kramer's website.
