I recently bought a GSXR 1000 K2. Today I put new tyres but realised that the front axle tightens but does not lock the wheel in position. There is about 5mm play ont the rim from side to side. I suspected a missing spacer but according to Suzuki the K 2 and K4 does not have a spacer to secure the wheel into place. I could only secure the wheel once I put the calipers in place. It doesn't seem right, what am I doing wrong? Please help.
