DaveDualSport replied to wcrhillbilly's topic in Dual Sport & Adventure MotorcyclesAs long as the ground is dry and not alot of loose dirt and rock, 80% street/20% dirt tires will go anywhere you want on an average dual sport bike. I don't know about the differences in specs for dirt/street rims As for gearing, I run a separate set for trail and street. Trail gears can idle and creep up the slow trails and give a more torquier feel to the engine. Road gears keep your bikes RPMs down at higher speeds and keeps the vibrations down as well. I run trail gears around town with no problems, but I stay away from long higher speed runs on the highway.
