This is all getting a bit much as Bob has now said I am evasive about iwis technical spec and whether it is fit for motocycles, he has even e-mailed iwis in Munich.
No chain supplied by any manufacturer is fit for purpose on a motorcycle given correct chain application charts.
Go to the Renold web site and put any bike producing over 30bhp into the free chain calculater provided. On a simple graph type pre selection chart even for 30bhp you need an 1" pitch chain, and even then it should be triplex. Which is why the major producers such as Renold, iwis, Sedis etc etc distance themselves from this market. So I doubt whether Bob will get a satisfactory answer from iwis or Renold on the matter.
Renold was always industrial it just happened that it was a superb product and worked well on bikes. As far as I am aware they only started recommending outer links after a costly failure in the USA. Even then they incuded a spring clip in the box as "a get you home" feature, which seems strange if the soft link is so good.
Bob I have never been evasive about quality, indeed I have spoken out regarding the lack of information from manufacturers. I know you have close links with Regina and I have no problems with that but unfortunately I have had enough of the fight and submit to your superior knowledge.
I now ask Laverda owners to contact you regarding chain issues and I will concentrate on my other clients, including those Laverda owners who trust me.
To everybody on here thankyou for your support and kind comments at times like this but I really am too tired of this thing with Bob.
