Yamaha YZF-R15 Questions & Answers

Spark plug. Swap it out and wd40 everywhere. My bike stalled on the highway in rain and that fixed it

With all bikes, it depends on many factors,
As long as you follow the service schedule and maintenance, these bikes will last a long time.
I've seen some uber riders with r15s with over 150k and running strong

It possibly did serious damage to the engine. If it was me I would refill the oil, see if it turns over ok and then listen for any strange sounds and then once it has warmed up slowly take it through the rev range slowly still listening. If you have a knocking or rattling sound it will be time to get a new engine or get it reconditioned by a professional. You should hopefully be ok due to great engine design of Yamaha. Good luck.

Depends a lot on your weight. I'm heavy and fairly squashed it at 110kgs being 20kgs less than the 130kg bike fueled. Someone 60-70kgs would have a blast on it. I reckon it'd hold 80-90kg riders. Over 100kgs and you'll find you'll get less out of it than lighter riders. After running in I found 7500rpm was an indicated 110kmh that was probably a real 100kmh. 8500rpm indicated 120kmh. Not a two up machine unless you and your riding partner each weigh less than 50kgs. Popular in Thailand and India with smaller riders. Well made. Handles poor roads fine. I rode my R15 in Christchurch with roads as bad as the one I rode on in Goa. Look up the Aussie guy who rode coast-to-coast on an R15.

According to Red Book prices the 2011 model had a trade-in value in the range $AUD1800 - 2200 and private buyer prices in the range $AUD2800 - 3300. 9000km in 3-4 years is not a lot, so try to find out if it was mainly used for peak hour traffic or similar commuting.
