I am crawling through FB and found a man,46 yrs old, with 160,000 miles on his 2015 ZX14r. Here is his post, August 2026.

"I have a bit over 160k miles on the original engine but I baby the bike and I am the original owner. Every 15k I get major service done valves spark plugs change coolant air filter clean. At 30k get all that done plus forks serviced. After my bike reached 10yrs I had my coolant hoses replaced with Samco radiator hoses kit I also updated my suspension have rear Ohlin's shock and updated fork springs."
Dan says he has a 70-mile commute and lives around San Francisco.

160k
