Depends on the bucket. Some are as cheap as $99.00 or as much as $500.00 (Mariah model). The other factor is there isn't an after market mount out there for a C-50 at least not a mass produced one yet.
not alot of these parts out there and they are pretty expensive too.
I bought a "generic" 3rd party mount and Jim2005 did a retrofit on it for me so my bucket would fit. Basically you'll need a blow torch to bend the mount to the correct angle. I haven't look for a mount in over a year so maybe someone has come up with one that fits by now.
it is ALOT easier if there were after market parts in the supply chain but I never found any. Tradewinds didn't even want to make a mount to fit the bike but wanted to retrofit a mount to fit mine. Of course they also wanted my bike for 3 weeks too to do the job. :roll:
