Parts and servicing
The basic service interval is 6000 miles, which covers an oil (but not filter) change plus throttle-body balancing and a fairly extensive list of minor lubrication tasks which are widely neglected, as is the spark-plug check. Plugs are due to be changed at 12k (but again it’s often skimped) along with the oil filter, and the head bearings and rear suspension pivots are due a greasing at the same time — which they usually don’t get. Valve clearances are checked at 24k, though they rarely need adjustment the first time, and the air filter’s changed at the same time. Brake fluid’s changed every two years, coolant every three and brake hoses every four. Access for servicing’s not too bad though there are lots of fiddly bits of plastic to remove. Spark plugs are a bit of a pain to get to, though.
New and used parts prices
Genuine Yamaha service parts aren’t too bad. An air filter’s about £23 and an oil filter £13.74, with brake pads £36.33 a set. Discs are £113 each, mirrors £40 and a front brake lever is £55.80. The aftermarket’s even cheaper though. Wemoto can do you oil and air filters for £5.28 and £10.20 respectively, uprated brake pads from £19.51 a set, a brake lever for £17.18, front wheel bearing kit for £7.49 and a chain and sprocket kit for around £100 (the genuine kit is a hefty £220). There seem to be plenty of MTS in breakers, but predictably they’re mostly there for crash damage, so front-end bits in particular are pricey - a good pair of forks are anything from £400 to £550. Front wheels are a couple of hundred quid too, and radiators up to £250.
