Just installed 16 tooth sprocket!!

Recommended Posts

I just installed my 16 tooth sprocket from Driven and I love it!! The DRZSM should come stock with this sprocket. I can cruise at a much higher speed on the highway and shifting through the gears is a lot better (gears are longer before having to shift). I can cruise at about 85-90 mph with the engine at about the same rpms as it was doing about 70-75 with the stock 15 tooth sprocket. Had some modifications to make it fit but well worth it.

Sounds like a good review. I need to got one to lower my high speep rpm's. How is first gear? Slow or sluggish? I have a S and would like keep the first and second power.

I do not really notice a loss of power in first and second. It feels the same as before except for I can hold the gears longer before having to shift, almost like a wider ratio transmission.

I would like to try this but I worry about first gear stuck in traffic.

Nothing worse then a bike that chugs while you are dragging the brakes constantly.

about 105mph top speed

My SM has never seen triple digits speeds with stock gearing or the 39 rear... :applause:

Max I have done was 95mph with the stock setup. Someone following me with a street bike said he indicated 93mph.

Did not have a chance to go WFO with the 15/39 which is nearly equivalent to 16/41.

Maybe I got a slow one... or a more accurate than average speedo :applause:

With the 39 tooth in the back is there still any bottom end at all?

In reply to those who worry about their first gear being too high for whatever reason with the "16" . No problem, I have the stock SM gearing and I almost always leave stop signs etc in second gear, it eliminates one shift and does just fine.....

I bought the sprocket specialists 16 for my s and it doesn't fit. There is another thread indicating the driven brand 16 fits the S, but beware the SS will not fit the S. Only the SM I guess because of the different swingarm.

Give us some info on the mods you had to make to get the 16 tooth to fit.

I had to slightly grind some metal off the the case where the clutch actuator rod is but only a little, the tooth barely touched it. Also the chain guide that wraps around the swingarm from the top to the bottom, I had to grind it about a quarter inch down at the center of the curve to clear the right side of the sprocket and the sprocket fit right on. As for the chain guard and sprocket cover, :applause: have not figured out how to put that on yet. the chain guard will not fit at all but the sprocket cover does not fit between the chain and sprocket anymore so I am looking for two spacers to space it out and it will work fine. I am riding right now without the cover on.

When I put my 16 on (Driven Racing brand) all I had to do is mill (or grind with about a 3 or 4 inch grinding wheel on a bench grinder or drill press at low speed) about 1/10" off of the case saver. If you do this, the OEM cover will fit right on. Done wrong or if the case saver is put on at an angle, the oem cover will not fit. To ensure no fitment problems, put the bolts into the cover, and the case saver, then attach it to the engine. Being the bolts are so long, the case saver is so flexible, it is easy to err and put the bolts in crooked. Remember, the bolts should screw in almost all the way easily by hand with no wrench.

i just ordered a 38t for my sm...Cant wait to get it on

Think you will find you'll have to shorten the chain by one link on a sm, so pick up a joining link when you get the 38 tooth rear sprocket. Bit of a pain, but a lot easier than all the hasle trying to fit the 16 tooth front.
