Gday Fellas, I'm after a bit of advice on the Ol' trusty XR600 or an XR400. I currently ride a Husqvarna TC610R 2000 Mdl and I'm going to get let it have a new owner soon, I think. My reason is that it is just TOO much of a handfull in the type of terrain I ride in 95% of the time and I end up wearing alot of trees and mud, the rest of the time it leaves everything for dead, which is always fun . That and the excessive time I spend on maint, and the servicing costs and parts costs are beginning to give me the shits . Oh did I mention that it hates transport legs between trails. I have spent alot of time on bikes over the years and can ride it to the limit with no problems before you tell me to go back to a 250! But I am looking for a "trail" bike not a "race" bike. Ok, here goes the questions. 1. I am 6'3 and 109 kgs (not fat either) and fit, so I need a good size bike for both height and build. 2. The majority of my riding is done in forest single track and fire trails, with lots of obstacles and hills that never end! 3. I want a bike that will not need endless hours spent with a spanner in hand, or waiting for a mechanic to open so I can get an odd size bolt! Now comes your turn! I have always liked the 600 for sheer grunt and the 400 for its flickability in the tight stuff. Tell me your reasons for backing which model! Pros and Cons! Sell me on it! Regards!
