Ok, i'll add one more comment. While plenty of people are replying saying that they ride trails with extended swingarms, it isn't the best setup. Sure you can do it, but it isn't the smartest way. A longer swingarm is going to handle worse, and will put less power to the ground. The best way to go for trails or mx is a shorter swingarm. If you should have to learn anything, its throttle control. You will hook up harder with a shorter swingarm (puts more weight on the rear wheels), and will turn easier with it. If you have so much power you wheelie everywhere, thats where the throttle control comes in. If you wheelie out of control, then you simply need to use less throttle. Trail riding isn't about horsepower, its about finess.
