If your speedo shows 150mph then it will be doing around 120 at a guess. Mine showed 221 kmh, 137 mph. It has newish tyres on so would be more accurate than older tyres. My tracker which has GPS speed said that it was 22 mph optimistic at that speed. |

Zitat von himoverthere im Beitrag #16 Legally, new they have to be within 10% (+4kph in EU) I believe. This is because it would be dangerous for a vehicle to be driving too slowly in a given situation. So the absolute slowest 150mph would legally be is 133-ish mph. I might test the gps later. You're talking 20%... which is waaaaaay illegal. www. thecarexpert.co.uk/how-accurate-is-a-car-speedometer/#:~:text=The%20law%20for%20car%20speedometers%20in%20the%20UK&text=A%20speedo%20must%20never%20show,but%20never%20less%20than%2040mph.

Yes, 10% up to the legal maximum speed limit. Try telling your tyres not to wear, end up with a smaller circumference and cause the speedo to be inaccurate. |

Zitat von spainy im Beitrag #15 Yes, the XR certainly does get there quicker but with an upright riding position it's not really a bike to be doing 150mph on. On my private test track, the RS actually feels more stable once you get to 120mph and over. The 2015-19 XR has fairly low gearing so some people alter the sprocket ratio to give lower revs at touring speed and potentially a higher terminal speed. For the 2020 model BMW have changed the gearing which, for me, takes some of the bike's nature away, turning it from the lanky, wild child to just another very fast touring bike. |

Zitat von spainy im Beitrag #20 it's the "loose" handling that makes it such a dynamic bike to ride - the new version feels like the sharp edges have been rounded off. This is not uncommon in the second generation of a bike. Think of how the replacement Fireblades & ZX10Rs were never as raw as the original. |

Posted somewhere on here is Teach McNeil's off-road video on the XR. Every time I watch him on the big bikes, I feel like I need to get back to a Suzuki 125 and learn how to ride better before troubling myself over the decision between an RS and XR. “A good man always knows his limitations.” |

Teach is a total badass. Saw him at my local BMW shop grand opening thrashing a K1600B for the crowd. |

Zitat von himoverthere im Beitrag #18 Tested it twice, yesterday & today, on cruise control at 101mph & 103mph for as long as it was safe to let the GPS settle & do a good calculation. ... & the speed read 97mph & 99mph respectively. Knowing that at an indicated 33mph I'm doing just under 30 ties in with this. It looks like the current system they use is take the calculated new-tyre speed & add 5kph. My part worn front & variations in tyre pressure would account for the extra mph. If I ever get back up to an indicated 150mph I'll let you know but I doubt it'll be for a while (it was in Germany), but all indications point to it being a real world 146, maybe 145mph... definitely not 120mph. Interesting thing to check though. Guess my 75 in a 70 is a bit high past the speed cameras!!!    F650, F650, F650, R1100GS, F650GS, R1150GS, F800R, F800R, K1300R, R1200RS, R1200RS, R1250RS |
