I got my new G310R Thursday and rode it home from the dealer in Iowa City which is 130 miles. We got the Hepko Becker bags on and a chain oiler. Rode about 30 miles more yesterday and really liking it. I traded an almost 5 month old Honda CB300F in on it which I had a little over 10,000 miles on and didn't get what I would have liked as they said it needed a new tire and chain etc. and had too many miles but don't want more than one bike. My wife has a 300GS ordered so anxious to get that; she has a Honda 300CBR that she will probably trade.

wife got hers home Thursday ad well, she dropped from ninja 500, she loves the weight, and handling, BUT lack of power and max speed of 85 not so much, def need gearing change and exhaust to make it complete, seat comfort...is the only complaint Id have with it but that getting modded today

cfaircraft I dont own a G310R as I am waiting on the GS model but the 85mph you talk about is not even close to its max speed. According to almost everyone I have talked with that have topped out their broken in bikes from Europe, Australia, South Africa etc. They all have taken the G310R to around 98 to 102mph or actually 158 to 165kph on the highway with stock configurations ( no mods ). So when your wife get hers broken in I suggest she really see what it will do Before you start thinking of changes.

sorry bud, that may be in those countries but in American MILES PER/HOUR the bike tops out at 88 miles per hour, and I verified it, and that IS what everyone I have spoken with claims as well, so not sure what your seeing or if its in kph, and hope your not expecting the gs to be any better due to body type that style usually a bit slower, which means on US hiways the bike will be cruising near red line which is not a good thing

I’ve seen several YouTube videos now showing the R running at 165 kph (while wringing its neck), which translates to 103 mph.

And at 70 mph, the engine is turning ~7000 rpm in 6th gear, which is still far from redline. My dealer (who has always been a straight arrow) told me he took the first one he got up to 90 mph without breaking a sweat.

WRONG, at 70MPH the bike runs 8300 rpm, which I have done with the bike, the wife has done with the bike, 2 diff dealers verified, BMW MOTORRAD verified, utube videos verified, Even went to dealer and test rode another with same results, so unless u have one AND have actually ridin it and can prove 1st hand pls no more wishfull thinking at just near redline the bike hit 93 mph, which felt like it was rdy to explode, so a little longer legs wouldn't hurt the bike at all as well as a little more torque

Performance. BMW says the G310R it produces 25.1 kW (33.6 bhp) at 9,500 rpm and a torque of 28 N·m (21 lbf·ft) at 7,500 rpm. BMW claims the top speed is 144 km/h (89 mph).

Might sound like a stupid question, but are you sure you were in 6th gear ?
Mine is certainly not running at 8300 RPM at 70 MPH. More like 7000 RPM (can double-check on next ride)

def in 6th gear and bike does NOT run less than 7k at 70+, verified with 5 diff riders and 3 diff 310, never said it doesn't run smooth, but it is a single cylinder and at upper rpm does vibrate, not bad but does fact of life, but not an issue, but the bike will not do 103 like some wished, that is fact, wifes only complaint on bike is it is NOT fast enough...that it, and only question was did anyone have any connection to sprocket source yet as the bike does need a higher end for hiway ops

assuming the data is correct, here is chart to reference. all mathematical, so real world will be off pending variables such as aero and weight. however, it's pretty accurate and very useful when comparing sprockets.

Well I went to the gearing commander website ( based on the chart above ) and pulled the data just as you did ( pwr2wh8 ) but put the max rpm as stated by BMW to 10,500 not 9500 and the max speed of stock configuration is 102.2 mph. I put in an increase of one tooth to the front sprocket ( 17 instead of 16 ) and the max speed rose to 108.6 . If I also lowered the rear gear to 39 from 40 it went up to 111.4 again at the max rpm of 10,500. At 7350 rpm's in 6th gear with stock gears you should be traveling 71.6 mph. With both the gears changed the speed at 7350 went up to 78 mph.

I am not sure what kind of max speed you want to obtain but dropping $600 plus dollars (front and rear gears + new exhaust system ) seems like a lot for a net max gain of 9 mph, not including the time and labor ( weather dealer or owner preformed ) required.

As another member put in another comment on this forum, if you have to keep adding things to a new bike to make it into something else maybe just maybe you should buy something else to begin with.

Just my opinion.

I also just calculated based on another website sprocket calculator that the combined change in gearing of both front and rear ( to 17 /39 ) will have a net loss of 9% torque. I don't think any current USA street legal exhaust system is going to give you back 9% more torque ( especially if you are in California where it is completely illegal to modify the exhaust system of a stock vehicle ). I also checked the Akrapovič website for technical data and they claim a max of 1.8 ft/lbs torque gain, but that is at 4900 rpms way below your cruising highway speed so wont really effect your top end performance. The Akrapovič exhaust systems are designed for racing and not street use in the USA and the gains they claim are with no catalytic converter installed. So I would do a lot more research before investing in something that may not do what you think it will or could land you in trouble with the law depending on the state you live in.
