Since we were already putting the new swingarm on we decided to do a few other things. We’ve been wanting to get rid of that heavy catalytic converter for a while so this seemed like the perfect time to upgrade to a full Akrapovic exhaust system. To help get a little more air into the engine we switched to a BMC high performance air filter. We also added a Power Commander to help smooth everything out. Last but not least, to get that back tire moving we stepped up to a DID racing chain.
