So. is it really just a difference of 5HP (or is it 10) does the twin cam rev anymore quickly than the old 1200 motor. Is it all about power delivery or what?? just asking is all...
the difference between twin cam and not twin cam
- Thread starter mark2jag
- Start date
The first thing you notice is that it the twin cam makes a much healthier sounding burble when you fire it up. Riding off, the increase in bottom end torque is noticeable - the bike pulls harder from low revs. Also, the rev range is extended by another 500 rpm in comparison with the '08 & '09 bikes. Although, unless I'm mistaken, the gearing is lightly lower to compensate so that you still hit 136 mph at the red line in top gear.
Mine's only got several hundred miles on in and just had its first service but I have noticed it's quite vibey between 4 - 5 K rpm and I've heard other people complain about this. Having just had the first service, I've been riding it quite a lot harder than previously and have been pleasantly surprised when I've given it a big handful and it's picked up the front wheel, even in 4th gear at one point.

Having ridden both a 2008 and 2010 twin cam GS the latter is definitely the better engine. Just that bit more pep and sounds better even with the standard can
much as schtum says, + the TC loves to be revved, unlike the older model 
no bad vibes on mine. man.

About £1000
The oil filler cap is now on the right hand side.
dont need to drop gears much, mid range a lot more responsive.
Having done about 45K on the earlier models and 8K since september last year on a twin cam I would say that the new engine is much nicer! Picks up and goes just that bit quicker and easier but it is a bit more vibey at 4K which is around 70iish mph which is a bit of a shame.

The difference is that is a Better Bike and on the latest bmw technology at the more expensive price
Twin Cam motor is the only 1150/1200 GS I have owned which I do not feel the need to swap the exhaust system on - it's that good standard 
Oh yea................ fuel gauge works on twin cam
My bike is pre twin-cam but I have test ridden a twin cam and found it to be quicker and a lot snappier off the throttle
That said the cost to change was £3k and it wasn't worth the extra IMHO

Not true, I've had 2 replaced on mine
The twin cam just feels more perky and sounds better. If you've got the cash then it's a no brainer for me, Twin cam all the way.
was at the bmw dealer yesterday and got to ride a gsa twincam for half an hour and must say the twin cam engine is picking up nicely out of very low revs and is very smoth above the 5 rpm mark..... I found the exhaust very noisy in slow sections what is nice somehow but I would bet it gets annoying on a long trip ?????
hopping back on my 2004 gs I was not sure what to be .......happy ..because i can drop it anytime without loosing a penny
or sad... because i don't have the best engine possible .
and PS ...the gsa fuel gage was not working ..

I don't find the exhaust noise at all annoying on long trips, but then I always wear ear plugs

Find I rev the engine more on my twin cam than my old GSA. Just seems to be more willing.
