I have replaced the swing arm bearings on my mp3 yourban a few times now.

But what a crap design, has anyone come up with a better solution.

When I first got a scooter I had the same issue on my Gilera and there was a guy in the UK called ShinyRed that made poly carbonate bushes. but not anymore.

By swing arm do you mean the exhaust support bracket (and rear axle carrier) or the actual swing arm at the front of the engine?

Much confusion has been caused on MV by the misnaming of parts.

Its the 4 needle bearings in the swinging arm .The engine bushes are ok as replaced them recently.
Bearings are in Red but also the number 13 + 8 get worn too.

Wouldn't it be simply easier just to replace the whole assembly as a single unit???

That's what I've always done (and what a shop always should do - cheaper by far on their time) - but before fitting fill up those tubes completely with grease. No way the bearings will fail again after that! Grease is cheap.
