I must agree, well said!:thumb:While most of my posts here thus far have been jack assin around I do have one thing to say about the best.
Quantify what you mean by "Best". Be it tires, head porting, exhaust or whatever. There are many variables in all of these things that could make a huge difference in what your looking for.
Trail riders, MXer's, sand riders and draggers all require different types of setups from suspension, tires, engine powerband and so forth.
You can buy the exhaust that makes the most peak HP but that does not mean its the best set of pipes for your desired type of riding unless your paper racing. That pipe may make the most power in a very narrow rpm range and would be useless on trails, but if your geared properly would be an animal in a drag race.
Basically define "Best" as you see it when ask for the best. Im done now.
