Hi guys,
So I have a query for everyone, my bike still has the standard chain and sprockets on its a 2001 curvy, has 9000 miles on clock,
I'm gonna change these while the bike is layed up over the winter ready for the start of the new summer season (not that we get much of a summer haha)
Anyway I'm just after ideas of what people are changing there's too, and if people are making any changes in sprocket sizes, I read up that the AFAM ones which are 1 tooth bigger on back and 1 tooth smaller on front are massively increasing people's acceleration and mid range performance for a slightly lower top end now my sv does 130 now anyway and to be honest I'm not to bothered if it's slower top end just wanted people opinions
Cheers in advance
Nath

Not sure what AFAM means. The naked SV ran one tooth larger on the rear if memory serves.

AFAM is just the make of the chain and sprockets like rental and super-sprock ahh right well that explains something then because I have the faired curvy and my pal has a naked and his pulls away quicker maybe down to the sprocket size eh

Not heard of that make, I usually go for DID and usually gold coloured as I like a bit of bling.
Same here, just put DiD gold one on yesterday, going to dig out the clear lube to show off the bling for a bit longer :)

I've got 14/44 on my 05 and 15/44 on an 03 and the 05 is far more fun to drive quick. There's a good 1000rpm difference between them at any given speed which would affect fuel consumption if that's a concern to you but apart from that it's a cheap experiment really.
The 05 still does 125 easily but like you said that's not really an issue, not many places nowadays you can do that and get away with it for long.

Ahh awesome this was the answer I was kinda looking for, I'm looking for the sv to be more punchy out of the corners and accelerate quicker than my mates sv and my other mates aprillia 750 . fuel consumption doesn't really bother me to be honest because it a hell of a lot cheaper to fuel than my car so even with the extra revs it will still
Be cheaper. I phoned my mate before he's a well known bike mechanic in our town and he said standard gearing on my model is 15&44 so he recommended to me maybe going for the same gearing set up as the Gladius, they are 15&46 and with that they have a quicker 0-60 at 3.5 seconds [emoji50] and ther top speed is 123 so I can live with that, like you say it's a cheap experiment for what sprockets cost so even if I don't like it I can always change back.
Thanks for the Info mate this really helps

That would work out ok, 1 tooth down on the front is worth about 2 1/2 up on the back so the Gladius gearing is much and such the same as I've got on the 05. If you can be bothered then either fitting a stepped woodruff key on the ignition rotor or slotting the pick up mounts to advance the ignition is another cheap route to more fun.
Every little helps.
And in an entirely unconnected manner, you've just explained to me why my unfaired SV fuel usage is a bit disappointing to me. I did wonder why I was getting iro 10% fewer miles out of a tank compared to the faired one, and obviously as well as the added wind resistance, I'm riding everywhere a few revs higher than I used to. Also explains why it doesn't pull very strongly from 80-90, when I had no issues previously cracking 100 on even a fairly short, straight piece of road on my commute to work.

Fitted a DID naked sprocket and chain set to my curvy. 1 tooth extra on the rear makes a nice difference. Much punchier through the midrange. Highly recommended.

Thanks for your reply mate, my mate who's also a bike mechanic phoned me today and told me the chain and sprockets are here, I got the DID kit in the end and I'm now very looking forward to getting it fit and seeing what it's like, if your saying 1 tooth extra was punchier I'm looking forward to seeing how much difference 2 makes [emoji16][emoji16]. He's gonna fit them for me next Tuesday, I can't wait, I normally do them myself but i don't have a chain rivetor and he has all the tools plus it's getting couple extra jobs done.
I'll let you know how I get on with it and how it feels [emoji4]

So just for anyone who is interested in changing there hearing set up, I've just picked the sv up from my mates and he's done the chain and sprockets for me it now has a 47 rear instead of a 44 and oh my [emoji7], it seems so much quicker now pulling away, I was just cruising in 5th and it had so much more pull when I went to overtake on the bypass, I haven't had much of a play about yet as it's like throwing it down but as soon as it dries up I'll give it a real test [emoji4][emoji106]

I find the standard S gearing to be buzzy enough for me, so I will stick to changing down for better acceleration Nath. A 7th gear would be handy.
i run 16/45 but i'm not riding in stop/start city traffic or doing much car hopping (nice open twisty roads up here in Scotland). was running 16/44 and it was a bit pushy into corners but the extra tooth on the back seems to be just the ticket. yes i sometimes get caught out and have to change down another gear on corner entry but its no biggie.

Your right about the 7th gear mate I often find myself looking for it [emoji85], so will be even more now but for the riding I do I'm hoping this will be the right set up [emoji4] all going well so far with it anyway

i'm in Fife but my sunday runs consist of as far north as Grantown on Spay and as far south as Hartside. St Marys and the borders is a my playground. Fletchers in Selkirk is our usual starting point when i'm down that way.
i wont see out the door for 3 weeks at the mo so for me there is not much left of the season as i dont do winter.

Ahhh kool man [emoji106], we were all just up hart side on Sunday morning there for Suzuki demo weekend was a good was totally packed out well over 100 bikes,
I'm the same really don't do much of the winter but I'll go out if I have to because I went from 16 to 22 without a car and my bike was my only mode of transport so I'm pretty used to it but became a bit soft now that I have use of a car haha
