I bet it's a lot less than that. Vehicles already run borderline lean due to emissions regulations; basically negligible, as several owners have stated. Plus it's overridden above 30% throttle, 4K rpm, and forgot which other parameters, so on a trip, it'd rarely kick in anyway.
Hey Tomp, so the RT has better cornering clearance than the C14? I had a 2014 RT that gave back to BMW due to the recall. Took it to the twisties once, and could take them as fast as on the sportier K1300S, with both almost dragging pegs the way I like to ride on the streets. I remember my 2007 FJR touching way earlier, but with the new Gen3, that supposedly got better. Hope the C14 is more like the RT and less than the FJR... although on most comparos I've seen, the C14 is slammed as the worst handler (and heavy-steerer) of them all, and the Gen3 FJR as the best. Who knows. Let me know your more detailed impressions:). Thanks.
Had an 03RT, a 12RT, and now an 04RT, in fact, the one I could not keep up with on the Sisters. Traded my 12 and its payments for the 04. RT's are much easier to take through the twisties than the 14. May be the tire size and profile differences, but the 04 is such a neutral handler at speed, any top end loss is made up in the turns. I still like riding the 14 more, but we don't have really twisty roads in my locale. Heard the FJR is still a little buzzy, and limited with a 5 speed, but I would like to ride one a while to see.
The '14 Buy Back, was not BM's fault, but the shock mfgr's. They recalled 8800 bikes and took back most, because of the problem. Something hardly any other company, bike or car company would do. Many took the new shock, and all has been good for them since then. Never got to ride a 15, but customers raved about them. tp
