I cant say yet as there not on my bike yet, But its PURE cosmetic for me, off course ill have them rebuilt and set up first... but i think USD's look better. At cadwell the NSR was faultless with its 15 year old set up, i only dialed in a little preload (no other options) and mine is just a standard R model, The rear is next, AGAIN cosmetic but im after an ohlins unit...Oh yeah 1 Plus is the bigger discs, should help it the stoping dept.
