Hi Ash,
Laurence White is a member of this forum - much admired for his ability to source all sorts of Benelli parts, accessories and other goodies.
What Ian was suggesting was that you send him a PM (private message) and ask if he has any front sprockets 'in stock'. Even if he doesn't have any at the moment he'll know where to source one. You can send a Private Message to "Laurencewhite" by clicking on the link in the grey box top-right of the forum page, just underneath the "
Welcome, ash1000rr" message.
I recently needed a complete chain and sprocket kit, which I sourced from
BikeTorqueRacing, so you could try them, but I'd check with Laurence first.
Hope that helps,
Cheers,
Dom
