I must admit I fitted Konis to my 97 +4 & am very happy as I couldn't see me clambering about underneath to reset them all the time. Plus I used them on all my motor bikes & never had an issue.

Trads don't have much suspension travel & having good tyres at the right pressures help. Make sure they aren't over 10 years old.
Good luck
