17t opinions wanted...

Did my searches, got the part# for the VFR 17t sprocket.

But one thing I noticed in each thread I read, it seemed quite a few people switched, and then switched back to stock or changed the rear sprocket also because they felt they lost too much low end....

Has anyone just done the 17t front and kept it, and are happy?

If so...... what kind of riding do you tend to do?

I enjoy a spirited ride, but rarely if ever go full throttle, and I am tired of looking for 7th gear...

Steel 17t is the best bang for the buck upgrade done, and didn't change the rear sprocket. Still ample power and moves the freeway buzz harmonic to a higher speed. Now it delivers "7th" for slab slogging, although in freeway traffic at speed keep it in 4/5th for better lane change punch.

i think the 17t may be the best mod outside a 16/44 setup

the 17 may deliver the best drivability of all, eases out 1st, stretches the top end enough that cruising rpms are often just below max buzz range

and yes, folks can talk about 'the loss' in the low end but again, i wonder about throttle managment, pin a 17t and it's 'more managable' than the 16 when winding out 1st in WOT and tryin to manage the inevitable front end lofting. this is why you'll here the 17t being discussed in drag racing threads.

again, it's such an inexpensive mod and the upside on the highway at cruising speeds makes it worth it, you'll just have to get used to winding it out more in 2/3/4 when first accelerating for a passing move or what have you.

I'm one of the guys who switched back to a 16. I was riding with an aggressive guy on an FZ1 at the time, and was outgunned in the upper engine rev range. I decided to make the bike a bit quicker. Went back to the 16, did the PC, Satos. The 16 is about right for me at Putnam.

For the rider that is less concerned with getting all you can out of your road bike, the 17 is a nice mod. The engine has enough torque to deal with the taller gearing. Very relaxed feeling at 70mph. I never saw an improvement in fuel mileage, tho. Side benifit of the 17, is a free speedo healer. I'd probably put mine back on here and there, but with my chain one link shorter than stock, it doesn't fit. Might look into a smaller rear sprocket.....

I went down 1 tooth on the rear of my 600RR. Much the same benifits as putting a 17 on front.

Finally put the 17 on this weekend. I had to add 1 link of chain, because when I replaced the chain I replaced it with a 112 link, so the 17 wouldn't fit. I didn't notice any difference in launching, I did notice a slight loss of "snap" in the throttle, but my spedo is correct, and the buzz was moved into A different range. Now 60 MPH is 3600 RPM.

Hi, I have the OEM 17th sprocket and I am happy with it. I have found that the tighter the course the faster the 919 is, even with the 17th sprocket. You can get on full throttle quicker and sooner with the 17th sprocket. In addition first gear is more usable. There is some loss of engine braking but is not bad, easy to compensate with rear brake. On the highway it is real improvement. I have not found that the roll on acceleration is affected. I have put on approximately 10k miles on the 17th sprocket and all is well.

Can you buy the 17t sprocket online or is it something you have to get from the dealer?

Hi, That is the one that I used. See attached. Do not forget the side spacers. I got mine from an online dealer and it was much cheaper then the local dealer. I seem to have the worst, local Honda dealer possible.

Check out this thread.

It pretty much covers the side play issue, if there is one.

Rob

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

Did you get the VFR sprocket(D20602) or the CB900F(D20603) sprocket?

I've been contemplating this mod myself, and it seems like most have used the VFR sprocket, but Sprocketcenter.com actually has a diff part listed for the Niner.

Thanks for all the help gentlemen.

I weigh right at 272, have stock gearing on my 9er and find it damned near impossible to pop a wheelie just by gassing it alone in first, Oh the steering gets light but nothing like I see folks doing all the way down the road.
My bike just moves out quickly, like it should. Maybe losing down to 200 should make it want to loft a mono all the way down the road. Might have to look into getting a 17t just to control it like ratdog wrote.

Installed the 17t sprocket today........

Wow, nice differance. How this is not the stock gearing is beyond me. Much more enjoyable to ride. Smooths the bike right out....
With my riding style, I notice only the slightest loss of acceleration..... if any.

Also installed some debaffled stock pipes...... sounds awesome....

Im joining the club. My chain is acting funny, making all kinds of crude popping noises & looks like its bouncing when I have someone else ride the bike (11,150 miles is all which seems a little lite). Between the chain & wanting to change gearing (I went with 17/44 cogs) I figured what the hell, got a chain tool coming too. Most people spend that in tatoos & spilled beer per month. All from sprocketcenter.

I am thinking of switching to the 17t sprocket myself. I read most of the posts about it and I wanted to confirm a couple things before I made the order;
Do I use the stock chain without adding any links or did you guys order new chains at the same time you bought the sprocket?
If you bought a new chain, how many links?
Do I need the spacers or not? It seems like it is split on guys that went with spacers and guys that did not. Does it depend on which sprocket you buy on rather you need the spacers or not?
Thanks.

Thank you... I'd just read through the whole first page and saw you already posted it there as well.


Anywho, does this one have the plastic or rubber to help quiet it, or is there any major disadvantage of just going with one of the cheaper ones?

Is this an easy swap, or should a shop do it? I've 2k miles on my 919, and would LOVE to do this swap.

I used the VFR sprocket so it would be quiet....

If you can adjust your chain, you can do this swap.

I finally got around to putting my 17t sprocket on my 919. I really don't notice any difference at all. RPM's are the same for indicated speed, so I'm still trying to shift into 7th gear when I get to about 60-65mph.

I did make a pass by one of those flashing signs that post your speed when the speed limit drops to compare before/after. Before the swap at an indicated 50mph on my speedo, the sign displayed my speed at 46mph. After swapping out to a 17t, the sign now says 50mph.

So it did drop the rpm's for a given speed, but now the speedo is dead on accurate instead of displaying a false higher reading than actual. At 50 mph, I'm still running 3000rpm, but now it's truly 50, not 45-46.

Does that jive with what other's have noticed? I guess I was expecting a more dramatic change based on what other's have posted.
