Had a nice ride yesterday 2-up on the TF into wide open country (Western Brook Gorge, NL) still lots of snow and excellent riding conditions - hard pack with just enough fluff to keep it cool. I must say the smooth power of the triple is very nice and my top speed on a lake with just myself and most extra gear (lunch bags/gas cans removed) was 150Km/h very briefly on a slightly rough lake with the snow a bit soft in the late afternoon. That's plenty fast but someone else said that they reached 150 with more to go. So I don't know if my 9" carbides and skisavers cause some drag? I switched for a short ride on a '09 non turbo Bear Cat that has a much higher seating position and a very roomy but uncomfortably wide seat. But no thanks on the feel and power compared to the TF - it had more of a utility feel to it for sure - the TF is starting to grow on me now.
BTW, I now have my torsion spring at the softest setting and it is still plenty stiff for two-up with no bottoming.
