So, max BHP around 120 isn`t it? That`s similar to many 900 to 1000cc twins, Superdukes etc. Over 74 ft lbs of torque too, nice.

Ah but that dyno run must be from a well tuned one no? 100 bhp a litre for bike engines is par for the course nowadays.

Yep, my lightly tuned 900 engine is 88 at the wheel - so assuming around 12/14% losses with a chain drive probably just over 100 at the crank.
