i looked on the search but couldnt really find exaclty what i was looking for. so here goes. i was wondering about how much the 14t front sprocket ACTUALLY does. does it feel faster? do the gears feel shorter/longer? how much does the acceleration change? is it easy enough to swap out? i am very interested in having my SV get a little more "get up and go" so any help is very much apreciated!! and if its not to much trouble some info on who manufactures quality ones and where to buy them for the best money would be great to! keep on ridin!

With Actually in all caps I assume you want hard numbers... I doubt you'll find any.

The 14t change is among the most common, the bike is definately quicker from a stop and pull much harder for a given speed in a given gear (it should you run higher RPM). The gearing is noticably lower.

Swapping it out isn't hard you will need a 32mm socket, a 2x4 to keep the rear wheel from turning, a length of pipe to act as a breaker bar, torque wrech (105 lbs I think), screw driver, hammer, and a few smaller sockets.

And I think Sprocket Specialists are the most commonly used.

If you do a search for "14t" you will find a bunch of threads on the topic

Nuthin' left to say but,...+1 on all of the above.

The swap is easy and what it will give you is more acceleration down low (at the expense of top speed, but not too much).

ive had the 14t front for a while and ive decided that i hate it... its cool to have that extra bit of oomph down low, but i constantly find myself trying to shift in to 7th gear when i get on the freeway. the bike hits redline in 6th way to easy. going from my stock 15/44 setup to 14/45 i think ive lost about 15mph off my top speed, and before i was just barely touching 10.5k rpm.. now im hitting the rev limiter before i know what happened.

so, if you ride only in urban areas and stay off the freeway, it could be good.. or if you ride a lot of tight twisty roads or ride trackdays at a rather technical(short, tight) track.. then go for it. it just doesnt suit my needs though, i need something a bit more versitile.. 15/45 or 46 i think

Top end 6th gear is like 125 or so so if it can still do 110 i would be happy is this reasonable or not?? I do my fare share of highway and twisty mileage so i would like the oomph. I rarely crest 100mph so i really wouldnt need to worry about the very top end speed.

I've hit 115 with my 14t front, but that's about it. I find the extra low end acceleration more useful for my purposes.

So you get a quicker low and mid-range at a sacrifice of top end speed, with faster engine wear, and less gas mileage :?:

Yes..and no. Yes- bottom-end performance is significantly improved; no- since engine wear is more dependent on heat cycles (how many times you start a cold engine) than operating time I don't see that as being a major concern; and maybe- with 14/45 I run ~6500 rpm @ 80 mph and get 43-45 mpg.

I run 80% freeway at a typical 75-80 mph cruise speed and don't look for seventh gear, although I will admit to occasionally leaving it in fifth!

Top speed is irrelevant unless you're on the track. With the lower gearing your 0-100 time (in my world 80 to 100 back to 80 is more important than 0-125) will drop. If 100 mph doesn't scratch that itch, well... :wink:

As with anything else, your riding style will affect mileage and and engine wear more than this mod. I know people with stock gearing who get worse mileage than I do, beacause they are consistently more aggressive on the throttle. I like the availabilty when I need it, it doesnt mean I have to shift at higher rpms if I do not want to.

 

[wonderjosh]

sorry i dont really like cruising along at 80mph with the engine turning 7k rpms.. its just .. annoying

although, i do like not having to downshift when i want to pass, just have to roll on throttle and there ya go.

 

[ronlarimer]

I used to look for 7th and now I don't shift to 6th or even 5th sometimes. I got used to teh higher RPMs and they don't bother me at all now.

 

[nc_sv650]

The number on the tach doesn't concern me, partly (I guess!) because of so many years with I4s and also because the SV isn't at all buzzy. To each his (or her) own!

 

[wonderjosh]

with airbox lid removed and aftermarket exhaust... its loud at 7k rpm for one thing, there is also a lot of engine braking at that rpm, so if you are lazy with the throttle it can be kinda jerky. when cruising around i think right at 5k rpm is most comfortable, can just chill and enjoy the scenery. now, if im in a hurry or traffic is crazy i tend to ride at a higher rpm to have the power right there so i can get around the idiots if i have to.

meow.

 

[Bloodhound]

One thing a couple of ya might be forgetting is that the naked model has a 45T rear, the SVS model has a 44T out back. That being said, one of ya is turning higher rpm with more braking and little more noise. How about comparing rpms at 75 or 80 mph between an S and N model? I would post but I still got my 15T F and 44T rear and was considering the change, but this is getting interesting.......

 

[wonderjosh]

mine is s model, but when i changed the front i also went to a 45 rear

Desnorkled with tank raised and a Holeshot. If I wasn't ok with loud I would still be running the stock exhaust (I think Singer made it).

 

[cyclerider105]

I'm bumping this thread, cuase it is a great topic and it just died! I'm trying to decide whether to go to 14/44 or 14/45. I have all the sprockets and I would like to hear some opinions!

 

[B.a.]

i have a naked 05 and was thinking of going up one in the rear because even though i do alot of high way riding i tend (now any ways) to stay below a 100 not to menion i think if your riding an sv to go crazy fast you might want to look for another bike because the fastest i've ever gone on mine was 135 (speedo) on a flat straight stretch on I-287 in 6th gear at WOT. i was thinking of just going up 1 or 2 teeth in the back just for $h1ts and giggles. see what kind of figures i get as far as top speeds in the gears and gas. but in all reality if you want to make the bike accelerate faster i would stick to conventional means i.e. exhaust, pcIII etc.

 

[mrlucky2u]

I went down to a 14t front, and up to a 45 tooth back, I can still hit 125mph, havn't tried to go faster than that yet.

Definatly faster off the line, IMO its worth it, makes the ride a bit smoother I think. Every once in a while though im looking for 7th gear on the highway.
