190/50 versus 190/55
« on: March 22, 2015, 01:16:46 pm »
I know that this subject was briefly mentioned previously but I have a specific query. Some folks on here and on other forums say that the K's handling is greatly improved with a 55 section rear,but I wondered if anyone had consulted their insurance company before making the change. I'd like to try the 55 but would not want to make an undeclared modification because of the potential opt-out by my insurer. I don't think that such a change appears in the standard modifications list used by most companies but someone may know otherwise.

The main reason as presented back in 2008 by BMW technicians in K13 inauguration for changing the tire fm 50 to 55 is the deference in weight distribution between those two models. Immediate result for that change lead to a wider tire for better grip in combination with Traction control, better power distribution, better and lower lean angle and finally a smaller turn angle.

A 55 tyre made my bike steer quicker as did Sandbars dog bones.

Don't get confused between steering and handling I could get my k with stock suspension to steer quick enough by turning the preload to max but it was like riding on rigid frame the trick is to get the bike to steer quickly and retain some decent suspension the 55 tyre is part of that jigsaw puzzle

As for the tyre itself just an evolution of the motorcycle tyre current sport bikes run a 60 as will sports tourers in 3/4 years time.

You could always ring your insurers Dusty and ask thaem directly, using a false name of course  8)

Haha, Brian. From the responses, it looks like the insurance aspect isn't on anyone's radar.

I've got two mates who run a bike breaking come repair set up just around the corner from me I see them every day so I've seen more than my fair share of Cat ABCD bikes and assessors half the bikes don't even have matching tyres.

Is it repairable is it a write off how much storage charge is there they wouldn't know a tyre spec from a bang on the head never mind a 50 from a 60 they'd probably be thinking your were on about PSI  :)

That surprises me, Chris. I have always assumed that they crawled all over it with a magnifying glass and tweezers. Knowing my luck, I'd get the one guy that does that!  >:(

You bin a bike don't get worrying about the tyre spec worry about who is getting their sticky hands on your bike unless your sparko never give up control of the it organise your own recovery to your house the moment you give up control there's storage costs bike breakers that have contracts with insurers all sorts of stuff.

My 2009 bike came with the 55 rear tyre and I believe back in those days it was listed as an option. Shouldn't be any probs with insurance though.

Not sure which bike you mean but I thought that the 09R was spec'd as a 180 tyre.

The important bit!! If you have an Ilmberger hugger for a 1200 phew it's tight fit with a 60 I sold mine and bought a 1300 version.

These folks are insurance relates guys.

The issue is not insurance, it is the SOCO you need to worry about if your bike is involved in a serious accident.

In that case Brian I presume you ride around in a single compound tyre because your bike was never supplied with such ;)
