Wondering if anyone knows about putting a 21 tooth cosa clutch in my T5 Mk1?
What sort of a speed increase can i expect? (the bike is Malossi kitted, Simonini pipe). I want to do a bit of long distance work and am thinking it could be good for those evening summer rides (!).
Are there any downsides to the upgrade?
Also, if i go ahead … can i use the old castelated nut to fix the clutch or do i need a special ‚cosa‘ nut as listed as an item on Sip’s site?
Thanks for responses!
