Hello from Devon. Real clotted cream comes from here.

I purchased a 2018 R1200RS LC at the end of summer. Years of avoiding BMWs after the wheel fell off the single side swingers of a K75 when I picked her up after a service. |

Zitat von Cooky im Beitrag #1 Welcome. The analogue speedo is useless as the numbers are too small as you say. I use screen #2 which gives me a large digital speedo. I don't have a pull to any side under power. Check your tyre wear and inflation. |

Zitat von Cooky im Beitrag #1 Hi Cooky, Yes the torque action of the in line crank is noticeable when you first get the boxer, but after riding one for some time your brain works it out and compensates for it, now after 20k miles i never notice it, many years ago i had an old R1000RT and a Honda CX500, now they were really bad, often got me into trouble engine braking and accelerating away from junctions. I have just ordered the new 2019 R1250RS, it has the new colour display, it might have been wise to wait for that one. Ged 2017 R1200RS grey/white/red. Blue 1250RS coming. |

I felt the same as you when I got my first RS. Liked it didn’t love it. Took me a while to relax into the vibe, as it loosened up so did I. I’m on my second RS (first one killed by a hit and run van driver). Ok I miss the visceral thrill of ringing the neck of a good inline 4, but I have come to love the bike. It’s plenty quick enough, it’s comfotable over long distances, it handles well, the ride is good, the electronics work, it forgave me when I filled it with diesel, and it looks pretty ace. (Well the Lupin and the red frame ones do, less said about the grey one the better😊) |

Thanks for the welcome notes. |

Zitat von Cooky im Beitrag #7 On the low settings the grips are just warm, on high they roast my hands and thats with grip buddys fitted, are you trying yours on high? Ged

not heard of a problem with the RS heated grips but there are loads of reports about heated grips on the S1000XR not getting to a decent temperature. Most likely a dodgy batch that mostly ended up on the XR but perhaps your bike made at a similar time and has a dodgy set. |

Zitat von wessie im Beitrag #11 It is actually the other way around - the lower the resistance then the higher the current flow and the more power is dissipated in the grip, with more power dissipated being equal to more heat released. If you are not convinced, then consider the extreme cases: for a broken or open circuit the resistance is infinite and no current flows so no heat is produced. For a short circuit where there is zero or near zero resistance then a very large current (not infinite but limited by the battery) will flow and produce a lot of heat and maybe even start a fire unless a fuse blows. The relevant formulae are as follows: V divided by I = R, where V is voltage, I is current in amps, and R is resistance in ohms, so rearranging this I = V divided by R. Therefore in example 1 above I = 12/16 = 0.75 Amps, and in example 2 then I = 12/7 = 1.71 Amps Power in Watts P = V times I Therefore in example 1 the power taken by the grip is 12 * 0.75 = 9 Watts and in example 2 the power is 12 * 1.71 = 20.52 watts. The lower resistance of 7 ohms in example 2 produces a higher current flow and therefore dissipates more power and produces more heat.
