Hey just wondering if anyone has changed their sprockets and if they are happy with the result, How much low end did you gain? How much top end  did you lose"? Wheelies easy after change? (which would be my desired result) And price?Any of your experiences would be helpful in making my decision

The classic 'easy' way to go is the 14t - at about $40.

Most everyone is happy. You'll gain a few hundred RPMs at the bottom. Off the top top- you'll probably loose none. Wind resistance will overcome the HP of the engine before you'd hit the rev limit in 6th

I expect wheelies would be easier. You are alerting the final drive ratio in the favor of torque vs speed.

- Though no 696 file presently.

Yes there is... ;)

Instead of the 14 on the front, I added 3 to the back. Same result, just doesn't make the bend as sharp on the chain with the 14. I did it when I replaced my sprockets and chain so the cost didn't vary.

There's numerous threads on this perennial subject, have a quick search and you'll get more opinions than you'll ever need.

My opinion aligns with this ^^.   Although I ended up going +4 on the back.

Whups - so there is. I'm a bit bleary eyed and 695 and 696 got IZ_.

So yeah gearing commander will show you ratios and theoretical top speeds. It just hashes gearing math - doesn't account for real world physics like wind resistance. But both cases of stock and +3 rear gearing show a top speed that's well in excess of the real world top. So at the end of the day you'd not loose any real world top speed.

Awesome thanks ! Now to hope it won't bust my waranty

My dealer installed the 14 tooth in the front.  The bend is pretty tight and if I let my chain get a hair dry I can hear it crying.  When I do new sprockets and chain I will go back to the 15t in the front and go plus 3 or 4 on the rear.

Why would it? The Magnuson–Moss Warranty Act in the US protects you. Unless you radically botch something and the warrantor can prove your claimed issue is related to the botch you're good. For example a changed sprocket would not void a claim on something like a bum ECU

I'd read that going larger in the rear as compared to 14t front is less stressful on the chain over time, but that the higher cost was a significant factor. However, I found the additional $45 to be a negligible tradeoff for what's supposedly more mechanically sound.

Despite having purchased a 14t front sprocket in anticipation of swapping it out at my 7,500mi service, I sent it back unused to Ca-Cycleworks THREE MONTHS after purchase (thanks, Candice!) and went all new 15t/48t/DID chain instead. I immediately noticed more 'get-up-n-go' on the trip home, but I found the bike cruising smoothly at ~85 rather than ~95 as it did on the way there. I've also found the fuel light to come on right at 100mi rather than the 110-115mi at which it previously lit up, but that might just be me enjoying the new Termis/ECU.

In the end, first gear jumps up to 25 MPH quickly, but struggles to stay smooth around 30 MPH before smoothing out again around 35 MPH. Second and third are where the real fun begins until I really get on it in fourth and fifth gear to hear the song that begins at 6.5K+ RPM. I don't attempt wheelies, but I'm happy with the result.

Recently replace chain and sprockets, went +3 on rear (to 48T on M696). Noticeable difference. Perfect for city riding.
