2019 YFZ450R SE
Over the weekend, on my 2019R, I installed the BNR soft throttle body spring, thoroughly cleaned and lubed my throttle cable, installed a trx450r throttle assembly mated with a trx90 throttle lever and lemme tell ya.. It is so worth the few bucks and time spent waiting on shipping to do. Throttle is so light n smooth. Omfg. Unless your heart is set on aftermarket, DO THIS.
