The starter motor on my 2016 ZX-10R (ZX-1000-SGF) has failed. The shop, East London Kawasaki aka Bacon’s Motorcycles, has the bike, and I’ve been told that some of the magnets have come away and one is broken. The bike has been fully serviced, and only 4 years old. The manager of the shop, Les, said that he would ask Kawasaki if they would replace the starter motor for me, indicating that they might do so for free, and the cost to me would just be for the shop’s labour of fitting it. As a new starter motor costs £519, I was hoping that it would be a free replacement. Any of you who know me, will be aware that I keep my bikes garaged, in good condition and very clean. I bought this one in July 2018 with only 3528 miles, and it has only done 9515 miles in total.
Yesterday I got a call from Les, and he said that Kawasaki have made a “generous offer” of letting me have a new starter motor for half price, which would be £259.51. Bearing in mind that I never skip on servicing and always get a fully qualified person/shop to do such, I don’t think that it is reasonable for a starter motor to fail.
I have subsequently found out from Les that Kawasaki gets the starter motor for this bike from a company called Mitsuba. He said that the only markings on the starter motor are “Mitsuba SM18 12 volt”. I have found out from a starter motor shop that most Mitsuba starter motors cost between £85 and £120, and the most expensive are about £200. However, he needs the full model number for it, as “Mitsuba SM18 12 volt” is a group of starter motors.
So my question, at last, is how can I find out what the precise Mitsuba model number is for my bike? The Kawasaki part number is 21163-0064.
Is there anything else I should consider when replacing this starter motor? I would regret spending £259.51 if it is possible to buy the same thing for about £100.
