I usually wouldnt tell anyone this but....
That bike is a major find and if it's in reasonable shape mechanicly, $2500 is a giveaway price.
The RS bikes are very desirable, collectable and a very nice ride if youre going some miles. In fact, if you arnt going to buy it, email me, cause I'd love to have a crack at it and will either drive my pickup or fly out to buy the bike.
Don't worry about it not being a real Motosport. The 82's are better bikes anyway! I recentlt bought an '82' RS and just took it on our first road trip together, to the 49er Rally last weekend. It's a great ride and I really, really like it! As I said before, not everyone can stand the ergos but so far, theyre working for me and the bike absolutely loves to run in the 75++ range or to hit the twisties. Just depends on how stiff you set it up.
I just love R-100RS's
