‘05 Zuma 50 Clutch size?

[mattyslimz]

I’m getting conflicting info from around the interwebs about the size of the 02-05 Zuma clutch sizes saying they are a 105mm and that the 08-11s came with a 107mm. I’m wanting to double check here before I go ahead and order a new clutch. I’ve also read that some prefer the 105mm clutch over the 107. My current clutch is pretty worn and with the summer coming along it gets super heat soaked stop light to stop light or while pulling wheelies. I’m looking for aftermarket preferably S6 torque control and an upgraded bell for cooling. Any insight greatly appreciated.

As long as the bell and clutch are for the same size you can use a 105 or 107

You could even use a 112mm if you found a good deal on one. I had one on my 2008. The 105 and 107 would be lighter though.

So the 02-05 were a 2 shoe at 105mm and 08-11s a 3 shoe 107mm?
I’m on the limb with the Stage 6 torque 107 with 107 450g R/T bell. Do you suggest another type of clutch? What are these Dr.Pulley HiT clutches? Are they best suited for the Zuma?

You could use any of the clutches 105, 107 or 112mm just match up to the correct bell. I personally like the HiT clutch and have used it for a few years. It has a mechanism that locks the pads to the bell and reduces slipping. Use the pillow springs if you like the slip feel your used to with other clutches. They have a positive engagement feel that I like. I used a Polini 3G that I didn’t like at all.

Dr Pulley have a video explaining how it works.
