I'm not sure a pancake motor like the R18 classifies as a high rpm, small displacement motor. Certainly not with it's 1802cc displacement, engine load and cam configuration running out of steam pretty quickly past 4000 rpm. It's a very low stress motor, and really the motor is never really...

If you can change how it runs with the flick of the switch, from rain, roll, rock, that tells it's not mechanical, it's in the ECU tune, with 3 completely different tunes, as least at idle. Valve timing is controlled by the grind of the cam, lift, duration, and timing overlap. They are all...

HD engineers, after much input from the public, decided to engineer in about 1/5th, or 20% of the vibration the M8 crank has over a Twin Cam. ie they got rid of 80% of the vibration with counterbalance on the crank. Even with 10.5 : 1 compression ratio on a 114 CI Low Rider S, the handlebars...

BMW and Bosch run a separate tune on Rock mode. The way they set up and map the engine mixture and ignition timing in Rock mode causes it to idle that way. Run it in Roll mode if it bothers you. Personally, I think it's stupid to design a tune that accentuates the lack of smoothness at idle...

I've ridden a Classic and a R18 B, and the answer is yes, the larger fuel tank and the 4.7" of rear travel shock makes a big difference if where you ride is rougher, or less maintained 2 lane roads, with cracks, tar snakes and perhaps even railroad tracks you need to traverse. The R18 B is...

I would not want a new bike that has to have a new wiring harness installed, and it's not done correctly at the factory. If your state allows it, I would lemon law the bike. It's completely unacceptable that they can screw up a brand new electrical harness on a brand new bike on the assembly...

Will you be filing a complaint with NHTSA ? Seems to be an isolated R 18 problem now if not happening on the R Nine T

What does your work order show for parts and fluids changed out as well as labor rate per Hr and # of hours of labor?

There's a special gauge inserted in that service manager's mouth that gives incorrect statements. It's called choking on his own sh*t that his mouth is passing.

I've no idea the number of R18 B or TC sales in the USA from introduction to now, but I would very much be interested in the number of headlight failures out of that total.

Please file a complaint with NHTSA as soon as possible.

I hope you're right, with your next service. You'll probably get put in line for the next time they have spare headlights in inventory. Could be a while, like currently 2 to 3 month wait. BMW just isn't keeping the part in stock, their idea of "Just in Time" inventory only works for bikes being...

Let's put it this way.... BMW hasn't issued serial # bikes that are affected by the defective headlight issue. So, until they do, assume all bikes are affected. I think they're hoping that most will break just outside of warranty. Then the $3300 headlight part price tag, plus labor is on the...

Test the light at night in complete darkness for accuracy of the beam shining it on your garage door. Take pictures and post them up here. If it's a problem, take a picture of the odometer reading as well as the date, and if need be, forward all of that as evidence in an email, to your local...

Does that bother you, how BMW stocks spare parts that are a known failure issue?

I've been so tempted to get a R18 B, but at 6' 5", the low seating arrangement, the mid controls, the awkwardness of the toe shifter and the rear brake, the inability to have any option for forward controls, the dismal functioning of that huge piece of hardware screen without GPS from your smart...

Never going to happen.... My VW Touareg TDI, even with premium leather seats, adjustable in and out and up and down steering wheel , AC, cruise control, adaptive headlights, and every other ding dong, contraption or GPS device, isn't comfortable after 1000 miles. Nor is it for me on a...

it wasn't CO2, it was NOX related. Volkswagen Audi Group and Porsche, mainly in conjunction with Robert Bosch, who supplies their MAF, ECU, and fuel injection system, had originally created 2 mapping systems in the ECU, one for manual transmission, and one for Automatic transmissions, to meet...

Iridium plugs in such a low stress 9.5 : 1 compression ratio motor that runs mostly in cruise mode at 2500 to 3000 rpm should last well over 50k miles probably closer to 80 to 100k miles, if properly regapped every 15 to 20k miles. 4 valves per cylinder really lowers the erosion rate from swirl...
