Don't bother with Progressives as they are too soft (about 0.85) for the R3. Get straight rate springs from Race Tech or other mfg. with a rate of 1.1 to 1.2. Then adjust the spacer length to get about 25% of the total travel (about 25mm) in settle with you on the bike. Use 7.5w to 10w oil and fill 10 to 15mm higher than stock. This will transform the front end. Not as good as quality internals such as Maxton, but as good as practical with the stock damper rod.
