Changing rear sprocket for better acc, curvy

Hi! As the title says, I never use more then about 80% of the top speed that is living in my 2001 SV650S curvy.
Is it a good idea to change the rear sprocket, to get better acceleration? Is it true that the nakes SV650 has fitted a different rear sprocket than the SV650S for better acceleration?
Is it this the sprocket I should use? How much difference will it be in top end, and acceleration?

Most recommend changing the front sprocket, by dropping 1 tooth, which is what I plan to do.

You could add 1 tooth at the back as well, but I think that by adding teeth at the back you start to have issues with chain lenth I think

Better acceleration but losing a bit of top end.

if you do any form of motorway(not sure what they are called in norway) riding then i wouldnt advise it as the bike sits near 6000 revs mark which is horrible, at 70mph. if not, then go for it, its a giggle, however you will notice that your fuel consumption increases, not sure if tis down to the rider giving it more, or the actual mod!

You can go up to 3 tooth on the rear but it makes the chain tight! The Naked chain kit is 1 tooth up on the rear and is popular mod.

I order from suzuki dealer a kit for my sv650 (99) and when they came the front was one smaller and the rear one larger.
Doesnt seem to make any difference which is good as I liked it how it was. With the orginal sprockets I had 137mph on the speedo when I was hunched in but have not had chance to try the new ones yet.

By the way SV Speedo lie so it might not have been that fast

Am I right in thinking dropping teeth on the front sprocket has an adverse effect on chain wear ??

I went up a couple of teeth on the rear sprocket, and to be honest, preferred it with the stock sprocket and will be changing back to standard when its up for replacement. Theres hardly any noticeable difference in acceleration.I'm sure I'm in the minority though.......

I had a 46 rear on my Curvy S.I tried a 14 front but did seem to be adjusting the chain more so went back to a 15 front and tried first a 45 then 46. Didn't seem to feel any busier when cruising and was deffo peppier especially as I was always 2 up.

Yes. A large effect on chain wear.

Change the rear sprocket, and use a longer chain if needs be.

A lot of my riding is on little back roads and being a tit in traffic, so I'm 3 teeth up at the back (from naked standard), which is good, but you are revving the nuts off it on the Mway. Like on the ecosse run we were "cruising" at about 8500rpm in top ... I'm not sure if this is good for the motor... but it hasn't gone bang yet.

In fact pete if my motor does explode I blame your duc.

The 'N' has a 45 tooth rear where as the 'S' has a 44 tooth rear as standard, I found a 46 tooth rear was good and added a little bit of oomph lower down.

I've been thinking of doing this when it comes time to replace my chain and I was planning to go 46 - 47 teeth on the rear sprocket.

As mentioned it would make the chain tight - would this be enough to have an adverse affect on suspension? Would, say, a 112 link chain be ok to use as opposed to a 108 or 110?

Cheers!
