Any potential downside I should be aware of as I consider adding a couple teeth to the rear for a little more zip?
More wear on the rear tire and on the rear sprocket as well. You will also loose top speed, if that is important to you.
I went a bit extreme with -1 on front and +2 on rear (14/42 set on carpimoto.it) along with a full termi exhaust and race mapping. Can’t imagine going back to stock settings.
One mechanic also told me recently that the -1 on front induces wear on the swing arm because the lower diameter of the sprocket means the chain will rub against it.
Interesting. What limits redline on stock gearing and why would the same limit not apply to +2R?The MTS stock gearing will not reach red-line in top gear. Consequently, +2R will achieve the same top speed albeit at a higher RPM.
Ok, pat yourself on the back for belittling questions. I don't ride at 90 much less 155mph. I ask to understand the mechanics. I don't have a problem with chug-a-lug, maybe your skills could use some improvement in that regard.All of the "reduce top end" replies are funny. Who in the flying f*ck cares if you can only go 155mph instead of 158mph? How often are any of us/you actually hitting top speed.
On the flip side, every single time you ride the bike, you have to manage the chug-a-lug at very low speed.
Bingo 100% ^^^^ gearing commander speeds are always assumed at redline (the RPM ceiling). Drag limits the Multi from reaching redline with the stock gearing.Actually making the bike lighter impact mainly acceleration. It has no significant impact on acceleration.
Air drag on the other hand has a huge impact on top speed. The faster you go, the more impact the wind resistance has.
At a certain speed, the engine simply hasn’t enough power to battle the wind resistance.
Sites like gearing commander, indicate the theoretical top speed based on the gearing but not considering drag.
