Now back to the stuff which is fun but deadly (unique combination of words according to local newspapers)
I already tested it for the guy in thread "disappointed owner of gs 150" (yea i know not recommended but a man's gotta do what a man's gotta do). Search the forums.
This thing easily goes to 8-10k rpm cruising at 65 km/h on third gear. I tested it to 115 km/h, which was max on the little busy Friday afternoon. I heard if you know the exact gear shift timing and rpm, you can hit at 130 km/h.
But stopping from that is gonna take time. The stop-distance for that is 30 meters according to my tests with drum breaks
Damn, what a pity
