Got this for a KTM DUKE 125. No more cold start issues! Great plug recommended! Also I think they last for a long while only done 5000 miles so far though.

An excellent spark plug. They converted my 31 year old Yamaha XS 400SE from being a pig to start to jumping into life at the first push of the starter. Highly recommended.
