Yamaha MT-15 V2 Spare Parts Guide: What to Buy & When

The Yamaha MT-15 V2 is the streetfighter sibling of the R15 — same liquid-cooled engine, same VVA technology, but with a more aggressive naked stance and lighter feel. If you own one, keeping it running at its best means using 100% genuine OEM parts and knowing your service intervals inside out.

This guide tells you exactly what spare parts to buy for your MT-15 V2, and when to replace them.

Service Interval Buying Guide

Every 3,000–5,000 km

• Engine Oil (10W-40): The MT-15's high-revving engine demands fresh oil on schedule. Use Yamalube or a Yamaha-specified semi-synthetic.
• Oil Filter: Replace with every oil change — never reuse an old filter.
• Air Filter Cleaning: Clean at this interval; replace if visibly damaged.

Every 10,000 km

• Air Filter (Replacement): Full replacement at 10k km, or earlier in dusty cities.
• Spark Plug: The MT-15 V2 uses a high-performance iridium plug — inspect at 10k, replace by 20k.
• Brake Fluid: Check level and clarity. Replace if it appears dark or cloudy.
• Chain & Sprocket Inspection: Check chain slack (20–30mm is normal). Replace if the chain has exceeded its stretch limit.

Every 20,000 km or 2 Years

• Coolant: Replace with Yamaha Long-Life Coolant to prevent corrosion in the radiator and engine block.
• Brake Pads: Replace front and rear pads if worn below 3mm. Always replace both sides together.
• Throttle & Clutch Cables: Inspect for fraying. Replace if there is any roughness or stiffness in the cable action.

Top Genuine MT-15 V2 Parts to Keep in Stock

• Clutch Cable — low cost, high impact if it snaps during a commute
• Chain Slider — prevents chain damage to the swingarm
• Handlebar Grips — worn grips cause fatigue on long rides
• Front Fork Oil Seals — if your front forks show oil leaks, replace seals immediately
• Radiator Cap — a faulty cap can cause overheating at city speeds

OEM vs Aftermarket: Why It Matters for the MT-15

The MT-15 V2's 155cc VVA engine operates at high RPM and tight tolerances. Aftermarket parts — especially filters, gaskets, and cables — often don't meet these tolerances, leading to increased wear and engine damage over time. Genuine OEM parts are designed to Yamaha's exact specifications and validated for the MT-15's performance envelope.
