Welcome Stefan. There's lots of upgrades possible. Perhaps check out some of the bikes and build threads to get some ideas. There is one thread started by extrapolator which lists most of the parts possible to obtain, you'll find it if you search. These SP's respond well to better suspension & geometry, 15/51 sprockets, air boxes & power commander combined with better exhaust and being made lighter. Enjoy!
