Very pertinent post. Thank you. I have been on Tourances for my 1150s for something like 200,000 miles, TKC 80s came on the latest bike, they are OK, but wobble like crazy at low speed, almost like the headstock bearings have gone....tyre pressure did nothing to alleviate it either. Very disconcerting. Start moving beyond 30mph and it disappears, but the rumble and vibration don't. I have had a couple of proper slides, two wheel slide, using the TKCs, which has meant I am wary of them now and ride well within bounds, I don't even press on. They have lasted Ok actually, they were on the bike when I go it and Phil can't remember how many miles they had done before I took over - I have put 6000 miles on and there is another 1000 miles left in the rear, the front has hardly worn. I am no hero, nor pretend to be, but I do cover a good number if miles on a regular basis - this week I have jobs in kent, Aberystwyth and Aberdeen, I have done 684 miles over the weekend, down to Cornwall and back. I take longer to get there, cruising at a steady 75ish rather than piling on - it make fuel and tyres go much further.
So, if I can get 6000 miles out of a TKC80 (only had them on a rough track and across grass so far - much better than Tourances for that!!) Maybe the Kaoos will last me about 8000 miles? If they are better wearing than TKC80s and you will be using the throttle far harder than I do - I don't think I have ever gone over 5000 rpm on any of my 1150s, it is quite fast enough without needing to. I like grip for the road, I need it, but I also need longevity. I have done 45,000 miles since May on my bikes, that would be 10x TKCs for any of the throttle happy chappies - I have used 3 sets of tyres! The TKCs are getting to their last legs, well the rear is anyway. So I think I will get a set of these - anyone who wants a front TKC80 with only 1/3rd of the tread gone is welcome to it for a few beer vouchers or a decent bottle.
Thank you very much for the feedback, very useful and confidence inspiring. That slope with the runnel, not sure I would be able to take my 1150Adv down there, but then maybe with someone for moral support I could. I have never tried anything like that for fear of getting it wrong, dropping it and not having anyone to help me pick it up.
I would be interested in a follow up on the end of this to let us know how long they lasted for full life. My Tourances I get between 13,000 (lowest) and 15,300 miles the most I got out of a set. They last OK, are great on the road but I have the fear of God of going off solid ground on them, or even wet leaves! Hopefully the Karoo 3 will be the compromise I need for miles, grip and confidence with the ability to allow me to go a bit further than the car park.
