i grew up on 250 2ts so i wanted the same power and class. Plus i like the power and speed. Great for open free riding too. I almost wish i had another 2t also for woods due to the little bit lighter weight, but i love the torque of the 450 4t. Im just a big bike fan. lites are ok but just dont have enough power under me. JW but have you ever had a big bike wide open under you? its insane! Bader now owns my supermoto and ask him how he likes the 426 power.
I do admit, i never use the full power on a track with my 450, but in the woods i go all out on it. When im at our practice area i catually find myself looking for more in a couple of the more open spots. I dont ride tracks much anyways.
