Suzuki DR 650
I have a 1998 Suzuki DR 650 with 12,000 miles on it and have thrashed it consistently since buying it. Bridgestone trail wings are great on the street, footpeg scraping good. Okay on fireroads, not good in sand. New chain and sprockets at 12k, syntec 5/50 every 3k miles.
No problems at all, lots of grins, and sad sport bike riders on tight twisties. At the dragon (129) it will beat my own ZX9, not by much but it will do it.
Dynojet, jet kit, gutted airbox, took spark arrestor bolts out of pipe for breathing. BIG improvement over stock.
15 tooth front sprocket, 44 back with 520 chain 8,000lb GSXR chain is what it needs.
With jet kit it does great with this gearing.
Best value for money and fun I have ever had on a motorcycle, and I have owned a bunch of them.
