Hi all,

I was told that there would be 15 tooth sprockets available, but it is looking like these are not going to come to fruition. I and some others, would like quicker acceleration in exchange for 10 or so miles per hour on the top end. If anyone knows of any source for these or if the Benelli can share with another brand, please let me know. I know that these are available for the TNT, but not the Tornado. The Tornado uses the same pattern and offset as the Mille on the front rotors, so perhaps there is a common front sprocket as well.

sprockets

The TnT, Tornado & RS all use the same front (and rear) sprockets, on my Tornado & RS I ran 15/43 ratio, heaps better. I actually used a 520 conversion, the rear sprockets are AFAM to suit Marchesini wheels and I ground the original front sprocket down from 7mm (525) to 6mm (520).

sprockets

Whats the stock Tornado RS tooth sizes, I'm at work and the bikes home so I'm asking now :D
How much for a front one?. also doesnt going smaller on the front cause the chain to wear quicker??

sprockets

Stock gearing on the RS is the same as the Tornado... 16/41, except the RS has an alloy rear sprocket.

A smaller front sprocket will accelerate chain wear but so what? It will also wear the plastic chain buffer quicker also, I don't think it makes a ton of difference to the wear rate.

Stock sprockets on the TnT are 16/36 but our press bike runs 16/41.

I'll get back to you with price & part number for the sprocket.

ciao

Re: sprockets

I was told that the TNT front sprocket wouldn't fit the Tornado. Are you sure that it works and that both are 525 chains?

Thanks,

Joel

front sprocket

I am using my ground down (520) 16 tooth sprocket off my Tornado on my TnT with no problems :)

Re: front sprocket

Okay,

I see. The Tornado uses a 520 chain pitch and the TNT uses a 525.

Thanks,

Joel

Re: front sprocket

Joel, the Tornado has a 525 chain. The width is 7.95mm, pitch is 15.875mm. The 520 is the same pitch, but only 6.4 wide. The 525 will last longer than a 520 because it has more bearing surface area, so wears less - but weighs more.

John has ground down his sprockets to allow a 520 to fit. They were about 7mm, but now are 6mm. He did this for his Tornado, and has now fitted it to his TnT.

Re: sprockets

j.o,
i'm running stock 16/36 and was going to change to 16/39 but might end up having to extend the chain? maybe 15/36 would be easier as the standard chain length would be ok (although the wear factor will increase) what do you think.

Front sprocket

Back to Joe's original request -

Does anyone know if the front sprocket will fit any other bike? (besides the TnT)

TnT gearing

Although I should put this in the TnT section.... the 16/39 will be fantastic; you will love it; it will make 1st gear a little too short but the wheelies :D

You have heaps of chain adjustment on the eccentric adjusters (I easily run 16/41 !); rotate the axle to the bottom of the cam adjustment range; this'll jack the back up (don't do it you have short legs), it will quicken the steering a little but more importantly, it'll put more weight on the front end for more stability and front tyre cornering adhesion.

Re: sprockets

Johnny can you give me the name and phone of this "any Benelli dealer". I have tried to get a 15T front sprocket amongst other small parts from several Benelli and European dealers but they all had trouble with Benelli. I have tried to email Benelli Aus for a dealer recommendation but obviously they are too busy to respond. (been almost 2 weeks).

Its a nice bike and would like to keep it for a while but if this keeps going i will trade it in for a MV SPR.

You sound like a real dick, I think MV might appreciate your business.

Re: sprockets

Thankyou, your opinion is valued.
I have just realised why the few dealers i have tried for Benelli parts have so much trouble getting any support from Benelli Aus.

Re: sprockets

Hi all, i actually got my standard sprockets from brabant motors as at the time kjm were just in the throws of setting up, a bloke has just been across the sahara on a tnt and in an article he says he has replaced his sprockets with renthal however i tried loads of after market dealers and no one even had them listed.
