R1300GS / the good the bad & the ugly

[Hann]

BMW are saying it`s still air/water cooled.
Do we know how much of the cylinder is now jacketed and if fully jacketed why are they saying it still has a degree of air cooling (air cooling of the water in the radiators notwithstanding)?

 

[Boxerlust]

Looks like the heads are watercooled so the bike is still air/watercooled like the old Porsche race engines…Or 1200/1250 GS…Saves weight this way.4mm bigger intake valves , 2 mm bigger exhaust valves , 4 mm more bore but 3 mm less stroke but no higher rpm limit means less piston speed but I wished they would have left the stroke alone unless they plan on raising the rpm ceiling on the 17 inch M-GS and possibly R1300S…

 

[Boxerlust]

And to make the cylinders symmetric the camchain is in front of the right and behind the left cylinder…The gearbox under the engine and the position of alternator seems to have changed too…Only the 3 bearing crankshaft is missing which hopefully comes next to make the engine perfect as in raising the rpm limit ! Look at what Porsche has accomplished on their new GT3 Rennsport which is a n/a 4.2 L boxer which makes 103 hp from a 700 cc cylinder….Amazing !

 

[Boxerlust]

A couple more tidbits…The spoke rims seem to be be new and the new forged wheels which look very good when you see them close up are 1.8 kilos lighter than the spoke wheels which is a lot less ! And the configurator lets you spec the 20 mm taller 220 mm front and 210 mm rear sports suspension with all colors but my dealer said it is only available with Trophy blue or 719 green which would make no sense for people who like triple-black or white knuckle better…As also wonder if they were cheating a little bit on the 12 kilos weight savings as the centerstand , passenger pegs , luggage rack are part of option packages now as also 1 liter less fuel and the lithium cellphone battery is 2.5 kilos lighter…Wonder what the real numbers are when they compare the real weight on the first tests as also how the roll-on , dyno numbers and fuel consumption compares to the 2019-20 EU4 1250s that ran quite strong…! And like the central locking on the bags / top case with charging plugs , practical storage compartment in the tank but in the end a real plus 6 NM and minus 6 kilos or minus 10 with the forged wheels could have been better considering it is now 11 years since the old gen got introduced which has aged very well ! Aluminum frame , 155 hp and 24 liter tank and I would have put a deposit down already on a Triple Black with Akra pipe , sports suspension and forged wheels !!!

I read somewhere, the panniers have built in lights ! Is this inside or exterior lights.

Interior lights for the panniers! You read it here first.

Never thought I ever needed lights inside my panniers.

Fuck me, is he still going on about it?

I have had the pleasure of owning and near 40k miles on my last, possibly ever, BMW R1200GS Adv. Heavier bikes, HP, electronic this and adjustable that does not add to the experience of riding and enjoying a bike. If I want it, well, I have a car that can do all that. Thanks for the offer but no thanks.

BTW it is going in for a service on Monday, just under 40K miles, very good condition, no corrosion, panniers, pannier liners, tank bag, mudsling thingy front and rear, Rox 2" risers, reworked suspension. If you know someone looking for one. Give a shout.

The sport brakes look like Brembo Stylemas ?! The rotors are still not 320 mm but grew to 310 from 305 mm…Also I talked to someone who got to testride a new R1300GS and he said the shift assist and transmission itself work really good and the Akra sounds nice & deep…! As for lights in the panniers that might come handy but I prefer aluminum bags that hopefully get light & and charge plug / central locking too…LOL Looks like Keyless is standard now for all bikes and I still dont know how the worlds first shock with variable spring rates works…Really look forward for the first test ride but the small tank and missing 10-15 hp on top as also linked rear brake will earn my current R1250GS-HP with Akra , Rally seat , aluminum bags , cast wheels , Tractive shock$$$ & HP foot pegs/levers its keeps for now because it is still a damn fine machine and plus 6 nm minus 6 kilos minus 1 liter are not worth 15 grand I had to come up with…With 155 hp , 24 liter tank I would have violated my own rules to wait and jumped on the new one in Triple Black if available with sports suspension and of course Akra , forged wheels and Sport Brembos and vario bags until the new alu bags in anodized black become available…But of course with a trunk light…LOL Also read the Telelever has the same top as the R1200S & HP2-S had in their days as also the axle up front as also for the swingarm mount got bigger…That is great for feel & high speed stability but top speed is limited to 141 mph…!? Saw also new Metzeler Tourance Next 2 on the bikes…Great tire !

 

[Boxerlust]

One more thing…What is a torsion magnet that the new shift assist pro uses ?! The drive shaft uses bigger U joints to make it smoother and the spoke wheels are also all new…Just wonder why they linked the rear brake pedal to the front brake ? Stupid for tight turns at steering lock using rear brake & friction point on the clutch !

 

[J biker]

In the real world, the weight of the bike being 12, 10, 9 kg…or whatever less is a good thing. But where that weight is carried is equally important.
tbh I am more interested in improved suspension that is actually truly tuneable (not just two or three pre-set values) and an improved gearchange. The 1250 greachange is vastly improved over older versions I have owned/ridden, but does have a LOT of room for improvement!

 

[ChazzyB]

Anyone worked out what a torsion magnet is, yet?

I'm dying to know...

 

[Boxerlust]

Yes the all new transmission is still made in Japan but the shift assist pro is triggered by a torsion magnet ? Wish BMW had better press material and show these things and explain alsi how the all new ESA with adjustable spring rates works ! Also if the weight savings are real with the center stand , luggage rack & passenger pegs which are options on the new one attached! Because filling up one liter less and putting in a Lithium battery and leaving the mentioned items off the 1250 would save you roughly 8 kilos…LOL Anyone else not liking that the foot lever is now linked to the front brakes ? And to You Reggie your 17 inch wheels wont fit since the front axle went from 20 to 25 mm diameter which is a good thing for more stability…The devil is as always in the details !

In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion is expressed in either the pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf).
Thus the magnet twists the angle of dangle assisting the gears and the rider to alter the velocity of the rotating primary cut gears without using any extra injection of fuel, ie twisting the throttle.
In the World of BMW this is very important.

I pulled my 1200gs out the garage today. Not ridden for a couple of months as having to much fun on the Xcountry. Initial thought what a big heavy bike. Admittedly once moving you do not notice but at stop signs you do.
I am 6ft and well built.

Many thanks for that. I feel enlightened. My BS detector is twitching a bit, though.

Roundincircles so the torsion magnet detects and gives the impulse to the ECU for a smoother clutchless shift or actively slows the gears in the trans down for smooth shifts ? This is new and exciting sheet as also I still dont know how the variable spring rate works with a second spring compressing oil in the shock and what spring rate we can expect…140 to 200 would be great with one spring even amazing ! Also the sport brake option despite being still not 320 mm discs I would not be surprised if the forged wheels get 5 instead of 4.5 mm rotors ! Also wonder why BMW decreased the stroke by 3 mm as the cylinders sit high enough for plenty of lean angle as the bike would have had 1350cc and probably 115 pound feet of Torque and 150 plus hp…Stupid move to decrease the stroke IMHO ! As also I like to see real weight comparo 1250 vs 1300 with passenger pegs , luggage rack and center stand attached to see where we are without any tricks like less fuel and lithium batteries that are harder to replace somewhere on the road…

 

[Boxerlust]

And what is your feel about the linked foot brake ? I think it is a dumb move for tight circles on rear brake and friction point at steering lock…Impossible with a linked front brake !

There’s a fundamental connection between the new bikes technical and engineering advancement and the opening of your wallet. The latter wont happen without the former. It’s a simple approach by BMW that has been applied ad nauseam for 100 years, which is about to be celebrated ad nausea.

I read somewhere, the panniers have built in lights ! Is this inside or exterior lights.

Along with central locking and a USB charging point
