NGK BR8ES spark plug, Kawasaki SX-R 800
The plug Kawasaki specifies for the two-stroke SX-R 800, two per machine, and the spare to always pack. It is the wrong plug for the Yamaha SuperJet's 701 head: its 19mm reach is too long for a head that takes 12.7mm.

Listed: 2003 to 2011.
This part is listed to fit every Kawasaki 800 SX-R year the archive records, 2003 to 2011.
How we know: the part's fitment record, and the archive's 800 SX-R model rows, 2003 to 2011.
Both plugs take a 14mm thread. What differs is the reach: the length of thread that runs on past the seat and into the head.
How we know: NGK's part finder, as this shop's pit box list records it (B8HS, 14mm thread and 12.7mm reach; BR8ES, 14mm thread and 19.0mm reach). The parts of a plug, its threaded end running on below the seat into the cylinder head, are US patent 4,810,929, line 76 of the held copy.
Not to scale.
