Default Difference between the Blue and Yellow Clutch Spring

Can't find a reference to see the difference between a Blue Clutch Spring and Yellow Clutch Spring. I see that the Blue one cost more but cannot find any information.

I agree, your listings is the most accurate I've seen. When I did a clutch upgrade (non-hydraulic) did some research and selected the 37807 pink dot that was used on Police Road Kings. This spring provided an upgrade "heaver spring" over yellow dot clutch spring originally installed from the factory.

Another reason I chose this spring as some were stating that the 37951-98 spring was a little too stiff having difficulty engaging clutch. Another person complained of developing a case of carpal tunnel.

I imagine this depends if his / her scoot was driven mostly highway, or city and factor in the strength of the individuals hand. If your scoot has an hydraulic clutch then this doesn't apply, then I would install the heaviest clutch spring available.

Just my two cents,

It’s a shame there is nothing available today that can measure white knuckles & big a$$ smiles.
