Who has experience with the SP200?

[VenomRS4]

Well, I'm looking to get my first real dual sport. I have my eye on an 87' SP200...really good shape with super low miles. It's 100% Mechanically sound and I can get a smokin' deal on it too!

Before I get it though, I'd like to hear about some first hand experience you guys have on it. How it rides and maintenance/repairs needed. Ive been looking at specs on them and I must say, I have a hard time believing some of them...29 horsepower out of an air cooled 200cc 4 stroke? Really? I was thinking more like 15hp.

I plan on putting some serious mileage on this bike so I'd like to hear some input.
