These are tig welded from 304 SS . 53mm sleeves. They are longer than our standard bars at 295mm so the lever protector can be fitted and the GP master cyl/short lever could be fitted in. Extra leverage and more forward riding position helps muscle the beast around and keep the weight more forward. Open ends on the bars anodised bar ends to suit are an extra $25 or threaded bosses can be fitted for extra $20
