30 tooth front Sprocket

[docdoru]

I Have my 30 T Sprocket 5000 km its still ok.

For the Original Motor 29 T Sprocket are the right one.

If you have Tuned the Engine 30 T Sprocket will be the right one.

What type of engine tunning?

[Spider Rider]

For every tooth you add your rpm drops 200 rpm. milage is about 32mph

I went through 3 sproketts from mells and striped the centers out of each in less than 1000 miles each. I have had one made out of stanless and he has plans for a 31 tooth they cost around 600 but worth the price as Ihave 7000 miles with no trouble (LFWMFG.com) 209 465 0444 in Stockton Calif. talk to Leo tell him Jerry sent you.

I put on the 30 tooth sprocket 3000 miles ago and it is still like new. A lot has to do with your right wrist.
I don't baby it and I don't over work it. If the retaining bolt is tight, there is no reason to worry.

[WackyDan]

If they make one that can hold up, I'd get one. I guess I'll wait and see.

[Freddy]

I could be wrong but I don't think they are available any longer?

After recently completing the 12,500km / 4 week tour with my sons a week ago, I had a chance today to inspect that pulley. The pics below show that the teeth are about 80% worn away, ruining the belt. So it's back on with the OEM pulley and new belt. What was saved in fuel economy was doubly lost in returning to standard. On a brighter note, you will see that the internal spline of the aluminium pulley is as new, as is the shaft - despite concerns expressed above. I believe that the extra torque (110ftlb) I applied to it ensured its reliability. The conclusion I draw is that the pulley retaining bolt should be higher than recommended (sorry Scotty but the engineering can be 'managed' to ensure reliability of the spline at least)

Owww, too bad. Maybe a steel upgrade will be introduced.

[challman]

My concern about the aluminum sprocket is even though it's hard anodized that's still only a surface coating. There have been a few stock steel sprockets that have worn the splines out so I don't see this one lasting too long. Time will tell I guess.

Yes but at least the shaft wouldn't wear out. That is a Huge and expensive job to replace

Torque to 110ftlb and no more spline issues -even on alu pulley. It is the inadequate clamping of the pulley to shaft, as stated in BRP bulletin, that is the problem - not what they're made of.

Well quite a few have been waiting for this.....I don't understand your' numbers though.....327,- $ export price...???????

Why risk it... the other ones that were sold wore out quickly...... the gains are so minimal--- it's just not worth it....

Why risk it... the other ones that were sold wore out quickly...... the gains are so minimal--- it's just not worth it....

The other ones were made of aluminum thats why they wore quickly the gains are not minimal i have a aluminum one that has 10,000 miles on it no problem and no wear with the new lower belt spec the lower rpm's is very nice at hy speeds, the gas savings is not much but wear and tear both to rider and machine makes it worth while a good steel one is just what we needed just remember everyone it won't work with an SE

[AMTJIM]

I was running dimension specs for a larger diameter rear that had similar or slightly slimmer width for the rear tire. Can't remember what the width was but a 275 would fit if I remember right and it was slightly thinner...wonder how that would do mpg/rpm wise with the 30 tooth. 4th would probably be the new 5th and 5th would be highway only.

How do you ascertain the wear to the machine? If the RPMs are a little lower, you cannot translate that to a longer engine life. The Rotax is a high-revving engine, last I checked..it has been conditioned for wear and tear for years. I certainly don't think that dropping the tach down by 200 is going to give you any noticeable engine life increase. For that matter, the obvious problems the extra sprockets have produced far outweigh any benefits.

I'd say long-term, you're more likely to have issues no matter what material they use. I'll go with the manufacturer on this one...if more sprockets are better, they would've gone this way...if we see them go that way in the future, we'll know...for now, I wouldn't play this game...no benefits, just headaches...

???? I guess it depends on what you mean by minimal. The gain is 7% on the gear ratio, resulting in only a 7% decrease in rpm. It won't result in a 7% increase in gas milage, but even if it did, that saves only 28 gallons of gas a year for a Spyder that does 12,000 miles. I personally don't see the benefit, but to each his own.

It also means about 20,000 less times the engine spins per hour of use that adds up to a lot of wear and tear over 1000's of miles it's not all about mpg it's about a much more relaxed spyder and all i can say is those who haven't ridden one geared up a little have not felt the difference if you had spent a few thousand miles with more relaxed ride you would fully understand the benefit people are spending hundreds on fender lites and all kinds of other wraps and so on so why should everyone jump all over someone wanting to spend $400 for a less buzzy ride? Besides 28 gallons a year =$112 x 3 1/2 years pays for the sprocket

the Rotax 990 is a high rev engine, so reducing revs may not necessarily be the panacea for engine wear ... quite the opposite. It has already been shown that greater tooth-count on the sprocket doesn't increase miles per gallon. My riding style usually has my RT-S topping out at 70mph for cruise. It's also the speed limit around here, but I pass at 75-80. The OEM sprocket and everything else presents a calm, effortless ride. However, cruising at 80, as someone else earlier in the thread mentioned, would bring one's ride into the "buzzy" zone just given the nature of the machine. The greater tooth count may mitigate that, but I haven't read a remarkable enough comment that convinces me it's worth the expense or risk (of premature failure) for the mod.

Despite the above, I do hail the explorers and tinkerers. They are like our test pilots.

Just for arguments sake....if you have the 30 tooth gear you can always ride around in 4 th and keep your revs up when it suits you... Mike

That must be why those diesel engines that turn 2000 Rome wear out so fast and the little high rev 4 cly engines go forever come on its only common sence that a motor has so many turns of life in it and every time it turns you use some of it up like blue nite said drive in 4 th gear all the time if you think it will make your motor last longer

I guess you haven't seen the BRP tech release about how running too low of RPM's will cause damage........

My main concern is damage to the main shaft.... which I had on my Spyder.. as have many others have had and BRP covered many of them..... but what do you think BRP will do if you have such damage and they see you're running a 3rd party sprocket??

I guarantee they won't cover the damage under warranty... they will blame the 3rd party sprocket.

That tec release has to due with the se clutches not being fully engaged under 3300 rpm using everyones logic on here im sure the motorcycle the spyder motor came from that had a 6 speed must be having all kinds of problems caused by those who shift it into 6th ,there would be way less wear if we all run at 7500 rpm in 3rd gear when we are on the freeway ,yes mods are mods and as far as brp coverage goes

Wasn't the shaft damage linked to the belts being way to tight....and the low RPM'S issue relates to the the SE'S , correct.....Mike ?????

It s 400 rpm for the 30t 200 for the 29t I hear that those aprillia s with the rotax 990 6 speed are all wearing out because the riders are using 6 th gear face it every body they took away our 6 speed to give us a reverse and a steel sprocket built to the same spec s as the OEM won't hurt a thing and is a benicia that those who have tried can feel and those who haven't are only talking and guess at the possible feel

Yup-- we got reverse in exchange for 6th gear from the Aprilla camp... but I'm not sure if the gearing was the same otherwise... and I'm doubting people used 6th on those bikes until they were well over 100 mph......

Too low of RPMS can cause damage.. regardless of whether it's the SE5 or SM5. I doubt 400 rpms will do much damage...just like it won't help much on MPG.

My main concern is spline wear...... as someone who had it.... you don't want it.. and if you get it... you sure as heck don't want to have to try and argue the point with BRP pertaining to using a 3rd party sprocket.
