finally received wifes new g310r, nice overall bike, but def needs a little help, I am looking to change either front or rear sprocket, it needs more travel/top end, does anyone have anyplace that is selling sprockets yet, I haven't been able to find anything yet, We plan to replace the exhaust to recoup some of the lost torque with the sprocket gearing change, anything would help........thanks

Not much luck so far...
The BMW official parts only offer standard gearing as replacement, no optional sizes.
And I did not find any aftermarket selling them yet.
As for exhaust: changing for an Akrapovic for example would let you gain a theorical 1.1 Nm of Torque (and let you loose a real $600). Poor figures to justify the investment it seems...

did some research so far theoretical increase with exhaust is 2.7 with a reduction in weight, minor but on a small bike def noticeable and through revzilla only runs $490.00 and they have price matching and ive found em for less so for that cost and if it helps.....after ive regeared it then worth it, the bike def needs the regeared, on US hiways it would always be running near redline just to keep up,

Difference in price and specs from your findings is yours probably concerns the racing version. I was referring to the street legal one with catalytic converter, which offers very minimal difference in term of performance vs stock.

Back on topic of sprockets so far I've just found 1 company offering something. It's an italian brand called Chiaravalli and at least one dealer offers them online:
https://www.redracingparts.com/engl...iaravalliFrontRearSprockets/bmw/G310R2015.php

Unfortunately no offering for front sprockets. So far it seems they offer 39,43,44,45,47,49 T REAR sprockets. So as you can see all of these (except the 39T) would improve the bottom end (quicker acceleration but slower top speed - not what you are aiming for. And the 39T would probably not have a big impact...)

Will post other findings as it goes..

tx for sprocket info, and yes agree on the exhaust, the stock seems like a waste of time and money, I am looking at racing exhaust, not gonna race...lol, but at least should notice some improvement

Remus had a Nice illegal exhaust without cat
Not street legal
but who cares

 

[cfaircraft]

[tonnetje]

Remus auspuff high exhaust

looked at the remus, again on their website only applicable to the 2017, model, don't know if there is a diff, and akropovic looks better to me, I had a remus system on my r1100s, and hated it, the only thing it did was make obnoxious noise, no better performance, I removed and sold it off

a bit late i know, but i found out about this post today. did you change the rear sprocket after all? if so which sprocket did you use (number of teeth)? did you find any aluminum ones?

 

[angiedave]

Why didn't guys get a bike were the out put of `sprockets` they are happy with, just my thing but she still looks and operates as standard, is it me ?

has anyone bought any parts from redracingparts, particularly sprockets?their products look too good to be true. i mean, how it is possible to sell a part (rear sprocket) for half the price (~25 euros) and also offer free shipping?
i found another website selling chiaravalli sprockets that cost about the double (which makes sense) :
Eurobike - Chiaravalli Sprockets
i wonder if it's a fraud site...

I just posted that link because that popped up when searching for sprockets but have no personal experience dealing with them.
A quick google search brings up mixed reviews... like they might not always have the items in stock and the delay before shipping can be quite long, and the communication with them not super-good. They also say "We only sell by Internet. It is not possible to contact us by phone or visit us personally" so that's not inspiring a lot of trust...

exactly..
on top of that, there is a banner on the top of the web page, saying that there is an extra 10% discount, ending the next day (let's say 19th).if you visit the site the 19th, the offer is still on (the banner says that the offer ends the day after) and so on..
unfortunately, so far i haven't seen anyone else selling sprockets suitable for the 310, maybe it's too soon since it's a new bike... thank you anyway

 

[greekgeek]

after a bit of research i found this company that sells sprockets suitable for the 310 r (since both bikes use the same sprocket i suppose it fits on the gs).

Their chains listed are for off road not street use according to RK chains.

didn't know that there are different chain types, i supposed that all 520 chains are the same, my bad. anyway you don't have to buy the chain, buy only the sprocket
