I'm pretty short, so I'm looking for ways to lower my bike. I've done some searching and found kouba lowering links. 1" or 1.5"? On their wbsite they say the 1.5" rubs the swingarm, how much does it need to be filed? Would it be a better decsion just to go with the 1"? I also read something about internal spacers in the suspension that can be removed, is that true? Can I do it myself or should I get it done prefessionally? Pretty pumped about my new bike! Hopefully I'll fit on it better soon enough! Thanks!
