Assumptions: workshop labour €95/hour, fuel 1.85 EUR/L, oil €18/L, chain kit €180 fitted, naked tyres €320 a set lasting about 8,000 km. DIY servicing removes the labour lines entirely. Your prices will differ; the ratios mostly will not.

What MT-03 owners actually watch

  • The 321 cc twin is one of the most abuse-tolerant engines in the class; oil on time is nearly the whole job.
  • 42,000 km valve checks mean most owners never pay for one.
  • Budget brake pads before anything else; the front is adequate and worked hard.
