Guys it's time to convert to a 1200/1250! lol After a stage 1 on my 48 I'm doing 60mph in 4th. Before if I had already switched into 5th around 70-75 I would cruise at 60mph in 5th if I had to slow down to it, but now if I drop to 60 I drop to 4th and it sounds and performs like it should. The bike absolutely loves 80 in 5th and I've had it to 110 pre stage 1 and it didn't sound stressed in any way. I'm still looking forward to the 1250 conversion that I'm no where near close to doing.
