Because I have joined the dark side... yes it is true. After saving up money to move out with my girl of 5 years, we broke up and I decided to go ahead and spend the money on a new bike instead. So I got me a 2011 CRF 450. The thing is, I always told people I would never go 4 stroke because of how expensive they are, and pound for pound 2 strokes are better anyways. Anyways, I've never ridden a 4 stroke. Is the transition from 2 stroke to 4 easy? What is the biggest thing you gotta get use to. I guess it would be the power being a lot smoother when delivered, and maybe engine breaking? I guess you might use the clutch/breaks less? I dunno. I like hitting jumps, prolly my favorite thing to do on a bike and on the 2 stroke I'm pretty much use to just having it in the powerband and keeping it basically pinned in whatever gear I happen to be in. I'm gonna break it in next week, going to make some visits to some indoor tracks... prolly not the best place to break in a new bike but what else can we do in Ohio? I guess we could cry. Also, do y'all recommend putting on a slip on muffler (silencer) instead of using stock? This bikes fuel injected so I'm thinking slip ons are ok... because I dont really want to buy a header too.. thats like 1200 bux : / Any recommendations? Am I gonna miss pinning the 2 stroker on the jumps or am I gonna fall in love with this bike?
