Are they mandatory? I cannot find my rulebook at the moment, and I knew someone would know. Thanks in advance.
case cover is required on the left side. I would go ahead and just get both. It is better to have them just incase, and that way when going thru tech there is no question and ruin your weekend.
You might "need" them, but they are not mandatory per the rulebook. They were on the prev generation GSXR's. And yes Wera 20, I'll be at TGPR. Kris
Here ya go: d) All pre 2001 Suzuki GSX-Rs must have engine case guards installed around the right and left sides of the engine, extending beyond the frame, and are subject to the WERA Technical Inspector’s approval. Case guards on the left side of 1995-97 Kawasaki ZX6R’s are suggested but not required. Yamaha FZR 400, FZR600 and YZF600 machines must have an engine case guard on the right side of the engine. Heavy-duty aluminum replacement covers may be used in lieu of case guards. Stock case covers with extra metal welded on to make them thicker may also be used.
