I do not want to lose top end if at all possible. i have a stretch where i can open it up and push the max. but if it is recommended to go with the ones in the link i posted i will do that. now if i can keep from losing mph i am in like flynn!!!
so do i order those Dr pulley slides i linked to? good or bad?
not sure what the 18x14 means though...
18x14 is the size, and that's the correct size for your scoot.
Regarding the top speed.
If you're lucky, the 10% decrease in weight going from rollers to sliders SHOULD
result in same top speed at lower revs. Lower revs mean less power available in
the top gear ratio so an incline can result in a lower top speed after all. In some
situations the bike CAN push a bit more so you get an even higher top speed.
On a downhill slope you'll definitely go faster, but everything above 50mph is
over the suspensions comfort zone, IMHO.
Better acceleration though is a sure thing in this 14 to 13gr swap.
Math says a 10% decrease in weight is actually closer to 12.5gr weights.
You can mix a set of 12s and 13s to get that, and actually have a spare
set, or possibility to try only 12 and only 13 and see which ones you like better.
Considering the price, that's what I'd do.
