butt I was surprised today.. headed out to a lil restaurant in the boonies.. my buddy was onboard my STROM... she is sporting staintunes and up 2 teeth on the rear sprocket. I was on my 1980 Zuke GS1100 with a kerker exhaust.. we did a rollon from 15 mph to 100 mph.. DEADASS EVEN.. he would pull me about half a bike then he had to shift sooner than me.. as soon as he shifted I would pull him as I was in higher revs which is just where the GS likes to pull hardest, then I would shift and he would pull me. wel you get the point.. when all was said and done.. up to 100 it was a draw.. I do believe the GS would prolly win a top end race but at 60 I am done w that $hit.. last time i did that I blew a rear tire at around 120.. NEVER AGAIN
