I have had a search around for you but cant see any bargains out there at the minute. Apparently the Beta replacement shock is a bit beefier than the old one and less likely to snap. Thick end of a thousand quid though
Try Lucas at the above site,he rebuilds shocks mostly BMW ones but he is very pleasant too speak too.
He machined a piston rod for my wilbers rear shock...
Mike..
Well done both steve's. Told you they covered all parts on broken main bearing on mine. Barrel,piston,crank all bearings,seals and gaskets all f.o.c. Great service.
