Hi

Planning to swap my stock rollers on 2015 125cc Primavera to lighter ones from newer i-get engine.
Stock ones are 20-15 -19gr
I-get ones are 20-15-16gr

Will they fit and will it make difference.
Im not happy with low rpm when accelerating
Seem bit sluggish now

The accepted theory says go 10-15% lighter. In general. So should be OK.
Have you weighed the ones you have or are you going by published numbers? There are some confusing numbers.
Also, there are sometimes different weights for different markets.
