4 cyl. Power range in 11500 to 14500 RPM. Similar to the GSXR250 which runs out of puff at 185km/hr. Complex motor and therefore higher servicing on the F model at least. No centre stand. Dry weight 163kg, which helps for longer distances but arguably a comfortable bike. Sporty feet position. Small 12 litre tank, but great helmet compartment (put your Macca's or KFC in the via drive through).
