Have two sets taking up space in the shed.
Bought a set for my first bike and never installed them.
Second bike came with a set and I never installed them.
To me, the plastic protectors on the 990 or the aftermarket carbon ones are enough.
Crashbars makes it a pain to do maintenance and just bend to shit after few hits.
The tanks take the hit pretty good, they just need wear protection like the plastic or carbon protector.
