I had 2, and im a big big fan..bit if you were adamant on a lightweight stroker i'd point you towards an RS Aprilia as its much less likely to have been club raced.
I got caught out on my second RGV despite looking over it ! (mint bodywork should have been a giveaway but I was young, dumb and full of c** to quote that guy in 'point break'
The 'M' RGV (which youd probably look at - banana swingarm, stacked pipes etc) also had the temperemental 3 stage power valves I think - mine were seizing and it wasnt a cheap fix. Ended up putting the older 2 stage valves on from the earlier bike...great fun
- It was like a bloody on/off switch when it hit the pwer band !!!
