ON DESOLATE DESERT ROADS... even made runs over the two 7 and 10 mile mountain passes we have in the area at speed over 120... and 150 when i was running against my friends bikes. if i had to put a number on it i would say 150 passes at the track, 100-125 passes at 150+, and easily 50 passes over the mountains at speeds over 120...

all that beating... and all the abuse a short throw can put on the system... and my 41k miles on my 6spd never did it a bit of harm.

all the hype about the 6spd being a glass box in my opinion is failures due to abuse and not it being weak in itself... i wont say it will hold up to 600tq... show me a transmission that can happily without an issue... but i will bet if you treat it right, use the right fluids, and drive like you should then it will be fine at reasonable power levels...
