Hello,

I have a superduke build 2008. I have the opportunity to buy an R rear shock. I occasionally do track days, my weight is 82 kg. Would the R rear shock better my bike for driving on a track?

I guess that there is more ground clearance and probably the R shock is stiffer.

Best regards

Michel

I would say no. This is partly related to your prefix adjective in your name and also because your weight+prefix does not require more than stock equipment. There are ussually suspension specialists at the track that can provide you with a veritible smorgasbord of mis and useful information. I would start there and then ask this peanut gallery to Whey Inn.
Why did you dump the a in your sign off?

Try search ... all have been addressed several times ...

The "R" shock is 10 mm longer. It's spring (the one that comes on the R shock), is IMO more well-suited to your weight. It's valving is definitely different than that of the standard. It's additional length is in the body of the shock; the overall travel is slightly less than that of the standard (no matter, unless you're planning to dual-sport your SD ...). Yes, squat will be less.

This will affect trail however, and more so if you run a taller tyre at the track (e.g. a 190/55). Most will advise that you put your forks down in the TCs as far as they'll go (but not beyond the tubes - not caps - flush with the top plane of the upper TC), or install a Nichols TC. A steering damper isn't a bad idea either (OE WP SDR one is junk BTW). You will find a range of opinions here on this latter point.
