In my own experience i have found that series 1 and 2 handle far better than any series 3 or GP i have ever owned,with both tuned and standard engines.Lamaddict wrote: ↑Thu May 24, 2018 3:16 pm I have never had a tuned engine in a Series 1 or 2 but thinking of putting a Quattrini in a Series 1, with a front disc brake etc. Question is how do thy handle with a tuned engine in? The bars seem wider and of course they are heavier but this many be an advantage?
Stiffen up the front end,and fit a lower seat and you're ready to go.
At present im re doing a Ts1 in my series 1. I've only fitted progressive springs, BGM dampers,and fitted a TSR seat .
It's always stuck to the road like glue.
