You can buy new Domino throttles (which were fitted OEM by Ducati) at a fraction of the price from
www.redracingparts.com https://www.redracingparts.com/engli...n/roadrace.php For the one that includes the choke (fast idle) button:
Part number is #356203 and is £62.48 inc VAT.
For the one that doesn't have the choke (fast idle) button:
Part number is #352003 and is £57.28 inc VAT.
This is the complete assembly including tube and OEM grips.
I've used them loads and although they're in Italy they deliver really quickly to the UK.
