I rode a DRZ400 (Roger's friend Marty's) and it had a TT Vapor. Very nice unit. Much smaller than I thought it would be. Fo me a little too small to see clearly when it was bumpy, but that's OK. It looked solid, well made, light, and very functional.
BTW, The
Dirt Rat cannot keep up with a DRZ400 on the trail, uphill, downhill or anywwhere. The
Dirt Rat does, however, have personality.
The
Dirt Rat, Roger and his KLX300, and Marty and his DRZ and I rode 30 miles of trail today. I LOVE this time of year when it's still light after work.
