I've had three of the 2007/2009 first model and loved them. I know the following model got a longer swinging arm, but lost a couple of horsepower. The model after that went keyless? The 350 got the power back, but if the engine mapping is like my Forza 350 (same engine), then it runs out of acceleration when you get the wrong side of 70 mph (or should that be the right side

My rides are often long touring trips (Round Britain Rally) and winter commuting. Sometimes two-up, with luggage. I'm under 70 kg/11 stone, so not too much weight to shift.
Especially happy to hear from anyone who's ridden all the SH300 models.
Many thanks!
