Testimonials

Engineering is exemplary!

"I’m absolutely blown away with the engineering quality of the kit you have supplied to me which has just arrived this afternoon, a day earlier than expected too. It’s totally comprehensive and complete down to the last detail, the engineering is exemplary and worth the wait and price. Also very carefully documented and packaged, excellent! I’m really looking forward to starting the fitting of it all, and it now means at my age I can now safely start to enjoy my Rickman knowing I will not have to try and kickstart it with the problems I did have". | Triumph Electric Start kit

A true work of art!

"I’ve recently received this one off flywheel manufactured by Ark Racing Limited. I spent hours carefully measuring and checking dimensions before submitting them to Ark. This is the result. "It fits perfectly and is a true work of art". | Judd AV (Indycar) > Reynard 94D (F3000).

No other kit that comes anywhere close

“I’m extremely happy with the magnificent quality of SCM’s and Ark Racings electric start kit, personally I think there is no other kit that comes anywhere close to its engineering excellence. The billet parts are outstanding.”

Not “one kick only” but “one press only!”

Now the work is done, my Bonneville T120 starts and runs perfectly with the electric start kit! Not “one kick only” but “one press only!” is better for my legs at 70 years old.

I've looked on in envy...

BTW Arkracing, I ju st wante d to sa y what a good job you've done on this. I've looked on in envy as pre-unit engined bikes all got an electric starter, thinking it could never happen to my beloved A65's. What you have produced looks in keeping with the bike and is a much superior effort than the starter fitted in the 1970's to the Bonneville. Many thanks from an arthritic old bugger. - Source Reddit 27/02/2025: Actual-Extent-2783
