If there is one, I bet it's Callisto Grey...

No I've a Quartz Blue bike which everyone knows is the fastest, and it doesn't do 150  8)

I have had two rear wheel punctures on RT's, the last one about three years ago was on a Dunlop Roadsmart which had less than 100 miles on and occured a week before a long trip down to Provence. Luckily the offending "joinery staple" had penetrated right in the centre of the tread pattern. I rang my tyre man at Automoto in Bellerby to ask if it could be repaired and he said he would have to inspect the tyre with it off the wheel. This was done as I watched and a repair was effected from the inside, not from the outside as is the case with the "get you home" plug method. That tyre went on to do about 6000 miles of mixed riding, sometimes two up and with full panniers and top case.

Thank you, so to clarify and quote, 'it is recommendation only and not the law'. Thanks for clarifying.

Clearly not the fastest colour then...

So do they recommend no repairs just for fun or could there just be a reason.

The reason is the glue they use is not rated to over 150 mph. But not an issue for us  . Found that snippet on the net, so not expert testimony

:clap: I got almost exactly the same gift, 100 km home  with the new bike and the next morning a flat front tire. No question, I plugged the tire for a careful ride back to the dealer and bought a new tire. The 1 in whatever chance that a plug will fail at speed scares this old guy.

Totally agree.  For the price of a tyre it's not worth the risk.  And we all know thousands have done thousands with multiple plugs, half price brake pads and the wrong grade of oil to save a few pennies.

I would rather have a new tyre, no question, but I guess for some they can't afford a new tyre every time they have a puncture. Just because you ride an expensive bike, it doesn't follow that you have loads of dosh to throw around.


I had a puncture on the front of my car this week, £18 to fix or £150 for a new tyre, £18 won over. Now I know a bike is different, but if repairs are sanctioned by the manufacturers, then don't really see the problem

Well, I went the new tyre option.  The tyre supplier I use (Micheldever) would not repair a Z rated tyre.  As mentioned above, it could lead to a difficult insurance discussion if the worst happened at some point.  So, swallow hard, I paid the man £124 and got a new Metzeler Z8.  What a brilliant bike though (now that I can actually ride it).  Thanks guys.

Did the bike have Metzlers on it then, or have you put a different tyre on? I live in Salisbury when I had a blow out, I was near Basingstoke, had two holes, so got BMW rescue to take me to Barnstormer. They did a good job, charged me £140 fitted for a rear PR4GT, but they did stay open to get me back on the road on a Saturday, so didn't mind

The bike came on Metzelers but I like PR4s though and had them on my old GT.  Metzelers are still a bit of an unknown, but they are just about scrubbed in now and feel fine in the dry, wet experimentation to follow.  The RT leans well!  The Z8s seem to tramline a bit on road markings and overbanding, but that might be me noticing more on a new bike.  I thought about calling BMW breakdown, but in the end it seemed quicker and easier to whip the wheel out (crucial new-bike bonding time) and drive it up to Micheldever as I'm just north of Southampton.
