4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Replacing the early 2-valve SE82J, the 2018+ Tricity 125 adopted the NMAX-derived Blue Core VVA 4-valve engine and 13-inch rear wheel, gaining Ackermann LMW geometry in 2023.
Oil & Clutch Mechanical Engineering Note
Sharing the NMAX 125’s 0.9 L dry-CVT Blue Core engine (SAE 10W-40 JASO MB), the Tricity hauls ~35 kg more LMW front-end mass, warranting 2,500–3,000 km oil changes in city traffic.
Garage Wrenching Gotchas
- Match cold pressure across both 90/80-14 front tires precisely at 175 kPa (25 PSI); even a 3–4 PSI left-right imbalance causes steering pull and uneven shoulder wear.
- After pothole strikes or tip-overs, inspect the LMW parallelogram tie-rod bearings and quad-stanchion alignment rather than forcing the handlebar clamp straight.
5. Frequently Asked Questions (FAQ)
What are the engine oil and rear hub gear oil capacities for the Yamaha Tricity 125 (MW125 LMW) scooter?
With an isolated dry CVT belt case, the engine requires 0.9 L drain-only or 0.9 L (0.95 US qt) with filter/screen (B65-E3411-00 (Oil Strainer Screen)) of SAE 10W-40 (JASO MB). Service the rear reduction hub separately (final drive 150 ml).
How do you accurately check the oil level on the Tricity 125 (MW125 LMW), and what are its service intervals?
Hold the bike upright on level ground 2–3 minutes after shutdown, wipe the dipstick, and rest it on the filler threads without screwing it in (threading it in reads artificially high and risks oil starvation). Torque the drain plug to 20 N·m with a new crush washer. Factory oil change intervals are every 4,000 km, with valve clearance inspection every 12,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the Tricity 125 (MW125 LMW)?
Fitted with 90/80-14M/C 43P (x2) front and 130/70-13M/C 63P rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 25 / 33 PSI (175/225 kPa) solo or 25 / 36 PSI loaded. Seat height is 785 mm (30.9 in) at 168 kg wet weight, delivering ~292 km per 7.2 L tank.
