• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Who makes a wide rear sprocket?

Can anyone tell me how to order the 89 tooth sprocket and if it needs a new belt for assembly?

Yes, you will need a new belt. The belt you have now gets tight on the smaller sprocket, won't even come close to fitting the larger sprocket.

2017 F3T - w/large sprocket.

Don

You need to consider this move carefully.

Yes it probably will need a different belt......and belts are VERY expensive.

IF.....you change the final drive ratio that much, the "nanny" might not like the rear wheel turning at a different speed than it expects.

It also might throw the speedometer off.

Of course, your gas mileage will go down.
 
That link is not valid. Trying to see what you are speaking of.

I know the F3S still has the larger sprocket and all the F3T I have seen have it. But there are no specific mention of it or photos on the 2019 BRP site that I can find.

If they removed the larger sprocket from the F3T for 19, its a big step down. Leaves only the F3S as the hot dog. The sprocket makes a significant difference.

Sorry but they all now have the 79 tooth rear drives, to check this is correct all you have to do is go to this web site.

Yes for 2019 only the F3S has the larger sprocket, AND..... only for Canada & the US. Bruce B is in Austraila.

Makes you wonder if BRP is removing performance from the F3 line so as to bring a higher performance option out next year....

Still, its a shame that the current models are slower than the previous. Makes the desire to upgrade all that much less.
 
The change of the pinion is perhaps the best way to give more acceleration to our vehicle, it is a pity that BRP supplies that 89 teeth only for the northern market AMERICA, I CANNOT UNDERSTAND THE REASON.
 
However I am more and more convinced to do it, there will be around $ 1000, but I believe that the expense is worth it ........ the reports
of the gearbox for now they are too long, when I put the sixth gear the bike has no strength and just a small climb and the bike begins to lower its speed!

Many years ago a …………….. Mike :ohyea:...…………. most of post removed
 
By now we have established that BRP has in its spare parts catalog a pinion 89 teeth, so it is no longer necessary to look for those who produce them, the problem is whether it is possible to mount it or not and hear it limping.
 
But then even if I mount a tire of a different height than the original (for example 225- 45/15) will the control unit become limping?
