So I recently picked up a 07 R1 for my birthday, JUICEBOX and I went out the other day even though it was cold to test the new chummon out. JUICEBOX and I took off up I-20 and then preceeded to I-459 when we began racing from a 2nd gear roll on. I was actually surprised on how the R1 kept up with the 10R i figured the 10 would walk on me. When i looked down we were running a 174mph and were dead even. The R1 I picked up is modded well but has anyone on a 10 ran a stock R1?? If so how did they compare??
