Posted September 6, 20231 yr This might be a really stupid question, but here goes: As I was riding in rainy Luxembourg what I noticed a day later that when I tipped over the bike a bit, water came out of what seemed to be 'breather holes' in the end of the swingarm... Now I only ever had BMWs with single sided driveshaft swingarms, so I don't know how these fancy chain driven bikes are supposed to work. But is this considered normal?
September 6, 20231 yr Moderators Solution @leclerq Yes, it's working as designed. The swingarm is a hollow casting with weep holes in each side, just forward of the rear axle adjuster block cutout. Those holes allow any moisture to drain out that might have entered through the rubber plug on the forward right hand side.

September 6, 20231 yr Correct, but just wanted to add a tangential comment ... Because the swingarm is hollow, some people use it to store stuff, like tubes. The access door is the rubber plug on the front right of the swingarm.

September 6, 20231 yr This is normal. Also, there are 2 rubber plugs in the swingarm. One on the outer right hand side, and one on the inner left 'leg' of the swingarm. This one is hidden by the wheel. Make sure both are in place and sealed. I think I have Yamaha disease...
