Mono Shock II RA Suspension Spring....

[4bangpower]

Kevin,

Does Yamaha offer stiffer spring options for the Mono Shock II RA on the '10 RS Vector GT? Thanks in advance.

The Mono-Shock II RA uses the same spring options as the original Mono-Shock suspension. The most popular stiffer spring to put on would be the 6.5Kg spring which is part number 8FU-47489-10-00. The stock spring is a 4.5Kg rated spring.
