Biggest/smallest sprockets

[FvnnyL3tt3r1ng]

Is there any info anywhere on the smallest and biggest front and rear sprockets you can run? I'm thinking about shortening my gearing even more so I'd like to be able to throw on a big front sprocket for street rides when the time comes.

Edit: Well it looks like 14t front is the lowest I can find for sale.....

[lgk]

I've seen 14-15 fronts, and 39- 60 rears.

Do you know where you saw the 60 rears at?

Edit: Found this, wonder if there is any cheaper. I'm curious if I could fit both a 13t and 16t front on the same chain with this...

Never tried the 16 tooth front.
I thought jt made a steel 60 tooth.
But i can't find it.

Aluminum. You're gonna be replacing it more often than a stainless steel one.

edit: I'm planning to go with 14 and 47 for city commuter. And according to the faq, 16t fronts cause clearance issues, so just fyi.

Ah good to know. Guess there's no real easy way to drastically change your gearing.

+2 in the rear isn't even going to be noticeable imo. I went -1 in the front and up 2 in the rear and it was just barely noticeable, but required me to get a whole new chain. I think the bike's stock gearing is honestly the best for city actually I would even make the gearing taller.... say +1 -4 if that's not too tall for the bike to handle.

Nice, but the article gives no info on city driving... Not sure if infinitewhiskey is going for fuel economy either. Spot on +1/-4 though

Are you still running that -1/2 set up? I just want a little more acceleration, now I'm not quite sure lol.

I think my bikes still running on stock chain/sprockets so I wanna replace everything soon.

Yeah I'm still running it. In my opinion, it just makes enough of a difference to notice it, I don't think it's worth the costs. I think if you wanna change your gearing at all you should go at least -1/+4 or +1/-4 for it to be worth your time. But like I said, I think the stock gearing is honestly the best for city, going +1/-4 is the best for highway....

[fishdip]

Its not really hard to make a 16 work in the front with a little bit of work

[FvnnyL3tt3r1ng]

Just wanna note today I did my first power wheelie with no clutch at all with the -1 +2 sprockets in 1st gear. Had no clue it was going to come up but it sure did...... The timing must have been spot on. I got up some speed, closed throttle all the way, snapped it open and liftoffff.

[cuong-nutz]

Driven makes a sprocket up to a size 54.

Did you need a longer chain for the the -1/+2? I am thinking of -1/+4. how many more links did you need?

Do you have a link for that one? I really think a 60t is overkill I'm still trying to figure how much of a ratio it is compared to other bikes...Certainly higher because the stock gears in the tranny??

I did need a longer chain. You definitely need a longer one for -1+4. I can try to dig up the order of when I bought the chain for my current gearing. -1 +4 sounds good you'll keep your street-ability (sort of) and have that added torque. I saw you on the other forum glad I'm not the only one riding freestyle on the 250!!

I'm thinking about going up in the rear more as well I just really hate to lose my street-ability.

Warning Lazy Noob Question


what are all the pros and cons of changing the sprockets? isnt it something like accel for top speed or vice versa?

[FvnnyL3tt3r1ng]

I got my chain from sprocketcenter.com and they screwed up my order and sent me a 110 link chain instead of the 106 link needed for -1/+2 gearing. I had to hassle with them to get me a replacement but they finally agreed to send me a new master link since I had used the one they provided. So you need a 106 link (not sure what stock is maybe the same??) for -1/+2 gearing I believe on the website it has a calculator for that.

Exactly, more torque to the rear wheel in exchange for a lower top speed. I personally still get up to 105mph with the -1/+2 gearing but that is at redline pretty much. It didn't make a huge change and it's why I recommend going up or down by 4 teeth in the rear to make it worth the costs. Then again, an argument could be made that only a slight tweak is needed.

we got a chain and both sprockets once for my boys 93 zx6, i tricked the stealership into selling it to him for 75$ it was this brand, but i dont know if it was this exact one.



around how much is the conversion kits for 250s and if i had to pick between shock upgrades vs sprockets which would be the better choice. i have a 03 pregen btw


also do you have any other mods that affect your top speed?

RK is the brand I have. I haven't had any issues with them but I'm no chain expert. If you buy all brand new you're looking upwards of $200 but I'd hit ebay up especially for the front sprocket. As far as suspension vs. gearing it's hard to say I guess it's whatever you want more I mean for ~$40 you can get a new gen shock but if you're not happy with your gearing it's only gonna be a bike with better suspension and gearing you hate.

I have pod filters and factory pro jet kit which does affect my top speed. If you lose your center stand you might notice a bit of performance improvement free at cost. I still have mine on....

You can call them and see if any vendors carry it but usually all vendors just get it drop shipped directly from driven. That was the case when I got the driven clip ons.

Reza SS runs 13/48 and Casey (ninja250) ran it too and said he can get it up to 85 without it redlining. I plan on ordering from sprocket center and going with the 13/49. I want to keep streetablity too since I commute a lot. I moved closer to work so I can get away with gearin it a bit but switching sprockets and chain may get tiring.

13/49 is decent definitely the minimum I would suggest. I'm still debating on the >54 rear sprocket..... I know the gearing commander website will tell you a lot if you haven't checked it out yet.

The 13t is the smallest they make and the turning radius is pretty tight for the chain. Either way, all the 250 stunters run them and have not had any problems.

Hmm. I was looking at Sprocket Center's website and they list having the Superlite 50t sprocket but don't list it with the chain and sprocket combo. I'm going to see if they can throw it in the package and I'll have the 13/50 combo. I I have the 14T and the 15T so I can just swap the 13T out for commuting.

106 chain for the 15/50???

I would need a 110 link chain to run that combo so I would just have to do with the 14T.

If I step down to a 49t sprocket and I can get away with running a 108 links. and still use the 14 and 15T sprocket.

[Racer x]

I have a stock length chain.106 links I think. I use 14~16 up front and out back I have 39~45. I can't use a 16x45 but I can get the same ratio with a different combination.

center stand, murdered. muzzy full. and plug upgrade. next thing i add is prolly going to be a shock upgrade since i take my wife out on it all the time.

Plug upgrade?

Def. upgrade your shock asap! It's necessary for 1up much less 2up riding!

just better spark plugs then the nasty ones the PO had on it. bought it with 6k miles. it didnt wanna start up too fast, with the new plugs it usually starts on the first turnover, most of the times surprising me lol.


now i just gotta find me a dirt dirt cheap shock. i wanna live in my own little dream world where i can find a newgen shock for 20$ shipped

[ElJokerr]

I bought two sprockets, front and rear, 16T and 38T... Unfortunately I didn't know the 16T wouldn't fit due to clearance. I still plan to install the 38T sprocket but stock chain is too long... How many links will I need for the 14/38 ratio?

102 links. Remember to always measure before you cut.

[ElJokerr]

I'm thinking to just buy one with the amount of links needed

[FvnnyL3tt3r1ng]

What exactly did the 16t not clear? I'd prob just take the cover off if it were that...

[FrugalNinja250]

The 16 is physically too big to fit inside the front cover. If you attempted to grind out metal to make it fit you'd be left with pieces of aluminum that didn't really accomplish much anymore. Running without a cover will leave your left foot covered with chain grease in time, as well as that whole side of the motor. I ran a 16 for a few months and with the 43 in the back liked the gear ratio spread. Living on very flat land it was nice, but in mountaneous areas there'd be a lot of down-shifting going on.

You're absolutely sure it's 102? I plan to order one toda
