Spring Base with Bearings
Performance Clutch Bell
There numerous clutches that can be used from NCY, Dr. Pulley, Stage6, KOSO, MRP, Malossi, Polini
Different brands can be assembled together for each custom clutch set up.
The MK II from KOSO for 150s and Stage 6 for 50 offer the most tunning of all the clutches without leaving Dr Pulley out which is a popular one for Honda Ruckus owners as well as GY6 150. A KOSO custom clutch set up will give the Dr Pulley set up a run for its money and I do think it will last longer than the Dr Pulley 181401
MKII from Stage6 with 460 Bell that allows for spring tension and chnaging of springs without removing clutch or bell from drive pulleys.
These builds can be as low as 149.99 and as high as 449.99 for a Linhai 300
