yes

 

You guys have convinced me to switch to -1+2 during my rebuild.

 

I love mine- added a little extra get up. I stayed with the 525 chain and sprockets though.

My only complaint is that highway riding is a little loud since the RPMs are higher but I'm only on it for a half hour at a time or so.

If you plan to take hour long trips on the highway (who does that on a bike anyways!), then stock may be for you.

 

+1 I've decided to get the -1+2. Only problem now is, I have to get a speedo healer which is another $100+

 

My opinion is that because road riders spend very very little time at wide open throttle or using the whole rev range there isn't a real benefit from altered gearing. The only benefit is really seen in first gear because for the other 5, you could just stay in a lower gear for longer; 1st gear will now be shorter and you'll need to change up earlier anyway. Most people get them (stunters excluded) to get more pull whilst cruising at highway/motorway speeds not when near the redline and not at WOT, if this is the case then you may as well just cruise in lower gear.

Drawbacks don't outweigh the benefits IMO, each to their own though, it doesn't bother me how anyone spends their cash.


Have a play on here and see what you think:

I have -1/+2 gearing and wouldn't mind going back to stock for an accurate speedo and lower cruising RPM's, which converts to better gas mileage.

 

soo its good to go with 15/48 on the f4i??

 

the speedoDRD from 12o'clock labs great! and it only cost $70

speedo healer is nice but you dont need it. 6th gear what ever rpm your going is mph your going. such as 5500 rpm is 55mph, in 6th gear only. and you can gauge as you go down in gears the diff each gear is like 5 mph less .

 

Except your adding about 20% more mileage on your bike.
