I want to switch to -1 +2 gearing. Is this a good setup to go with or does anyone recommend anything else?

thanks

 

I have that set up, and aside from the high rpm when cruising at 70, I love it. The bike is alot quicker on acceleration. Gas mileage takes a hit due to the higher rpms though. Off hand I want to say I'm at like 8k rpm @ 70mph.

 

Which brings me to this question: For the trackday junkies: Are separate sets of sprokets and chain necessary to switch gearing ratios or can the same chain be used?

IOW, Will I require an extra chain if going to a tight, technical circuit day 1 and then changing gearing for day 2 to a circuit with long straights and then day 3 back to technical? (did the wording on that make sense??????[:-])

 

I have this setup....

as for the original post, its a popular gearing but its really only a popular gearing because EVERYBODY talks about -1/+2. Not all bikes are geared the same stock so going -1/+2 is different on every bike. For example, its the most common for the F4i and 600RR but the F4i has a two teeth larger rear sprocket than the RR stock so going -1/+2 on the F4i is like an RR with -1/+4. Totally different but everyone is so used to seeing -1/+2, its become the standard

you really shouldn't need to change the chain for gearing with a decent collection of sprockets (2 fronts, 3 rears usually will do it). I've never had to change a chain to get the gearing I wanted. Ed Bargy has a cool gearing ratio chart that shows gearing ratios from low to high with all the different sprocket arrangements that can be used to get each ratio. So for example if you decide xx/xx sprockets are what you need find out they won't fit, you can look at the chart and see what other combos will make the same ratio but allow for a shorter or longer chain

 

i literally just asked this question in a post (its still on the front page of this section) and people replied saying it wouldnt affect gas mileage... so whos right?

the title of the post is "Sprocket questions" or somethin like that

 

yes it pwns, best mod I've done on my bike IMO

 

With this mod you get better acceleration and lower top end speed. In exchange you loose fuel economy.
