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.
