I didn't understand jimoi said "a few small issues". We've never done anything together, so what do you know? Check at http://www.offroadvietnam.com/eng/22.php and see what our customers said about our services.
More bike options (Honda road bikes and motorcross) are available. We offer free upgrade from Minsk to Honda 160cc until the end of 2007. Latest comments about Honda road bikes at http://www.offroadvietnam.com/eng/22-65.php
I've had a few of our clients from Laos run with them on tours and the reviews have been good. It was disappointing for our clients to step down from 250 Honda to a 2 stroke Minsk but one thing that is certain, VN has pretty stunning scenery and any bike you are on is worth the ride.
I know the black XL in the photo and like other operators in VN, things are moving up in cc scale and this is a good thing.
