I think you'll find this is standard and the ones you've seen have been fitted with aftermarket sprockets, most OEM front and rear sprockets have rubber dampers. Admittedly I don't know for sure about the VFR4 but I remember a friends NSR125F for example had them.pugparcels wrote: one question - the sprocket is a standard 40t but it has a rubber 'guide' around the edge of the sprocket this sits just below where the chain rests. i have never seen this before was this another speciality made just for the vfr? or is it not a original honda part?
EDIT: Looking at http://www.bike-parts.fr/pieces-promo-4 ... 1300-.html" onclick="window.open(this.href);return false; and it very much looks like it has a rubber damper as standard.
