Just a few things to be aware of running a GP 125...
-Clutch life will be measured in laps. The start takes such a toll with a 125 that it's not uncommon for the rider to adjust during the race.
-Top-end life isn't long...be prepared to buy lots of rings/pistons. Such is the care and feeding of 2-strokes.
-For someone your size especially, you can really affect the bike's behaviour by moving forward or backward on the bike, because they're sooo small.
I'd love to have one, but one 2-stroke race bike at a time is enough. I've talked with Rich at Rising Sun Cycles (http://www.rscycles.com
), and he's got a nice selection of bikes and parts. Fun stuff.
Oh..disregard the attachment...this browser (Konqueror) is a bit funky or something. There's nothing there.
