I am basically looking to supplement my main road ride (Bonneville) with a more gravel and patchwork backroad friendly bike. Not purely an adventure bike. And I want to do this on near zero budget. Option A: My currently well sorted slightly modified '92 Suzuki GS500 (with '04 4gal tank)... this bike runs awesome and I have raised it about 1" or so as well as reworked the foot pegs forward an inch and down about 3.5 inches to allow for standing and more upright comfort. KX-bend alloy handlebar. 14t front sprocket. Wheelies in two gears if you want, comfortably cruises at 60mph but gets noisy and revs real high if you go much faster although it has plenty of power to easily run 90+ even with the current gearing. I've gone through this bike bit by bit over the past three years and it's really done right. Only thing holding it back from being very good on gravel and our bad backroads is the pure street tires. A set of 80/20s would make it pretty good, but it just feels kind of heavy and not enough suspension travel if the gravel roads get particularly rutted. Option B: Sell the GS500 and replace with... probably a DR350SE. This is the other side of the fence. I think this would require also 80/20 tires just to be streetable enough to get to the gravel from the suburbs where I live and would be running close to flat out on our 60mph highways while the GS is doing it with room to spare. But it'd be 60lb lighter and more capable on rougher gravel roads. Plus it's more of a contrast to my Bonnie, and it might be something I could take with me and ride on the beach whereas I don't think I'd ever try to ride my GS500 on sand. But I could probably sell the GS and buy a later-model DR350SE and it'd be a wash price-wise. What would you do? And if I do stick with the GS, what's a good choice of 80/20 tire that comes in 140 and 110 sizes f/r on 17" wheels?
