The first new sized front tire in 147 years. I wonder if it will be better than the old tire??

I bought one and the intiial report is very good. Great traction on the frozen ground.

my girlfriends dad runs a 90/100 on his 1984 yamaha tt600. ktm runs it on all there bikes. 80/100 is old but works well for most people. the 20in tires never took off unless ya had alots of money like the pros.

The tire is a brigestone 401F. Rocky Mountain has them for 49.00

Which also means Thumpertalk will probably have them as well. I live close to RM so no shipping charges.

The Dunlop version is suppose to be available in the first part of 05. I believe this 401f is the tire chosen for the front of the Suzuki RMZ 450. They are also using the 120/90-19 on the rear of the new bike.
