What to expect when riding:
This bike is for the experienced rider only.
The brakes are very strong, the whole package handles very tight, solid and predictable.
Power is strong with good low rpm torque, and very strong up to 5500rpm.
After 5500rpm engine starts to hit a 2 stroke like powerband, as front the end is lifting or gets light. Sometimes even in 3rd gear.
Although this bike is a bit of a handful at times, it can also be ridden sensibly on the road. But care must be taken.
