The Lexi 155 and the SH Mode 125 are the “sensible premium” options from Yamaha and Honda: one step below the SH160i and NMAX flagships, one step above the commuter fleet. Comparing them is really a question about value: what does the extra engine capacity and lower price of the Lexi trade against the SH Mode’s badge and 16-inch front wheel? Figures from official Yamaha and Honda Vietnam pages (retrieved 23 September 2026).
Engine
Lexi: 155.1 cc Blue Core VVA, 11.3 kW at 8,000 rpm, 14.2 Nm at 6,500 rpm, 2.19 L/100 km from a 4.2-litre tank. SH Mode: 124.8 cc eSP+ four-valve liquid-cooled EURO 4, 8.2 kW at 8,500 rpm, 11.7 Nm at 5,000 rpm, 2.16 L/100 km from a 5.6-litre tank. The Lexi is clearly the stronger engine; the SH Mode counters with a bigger tank and near-identical published economy.
Wheels and ride
SH Mode: 80/90-16 front and 100/90-14 rear - the SH-family big front wheel, the best pothole behaviour in the class (our 16-inch wheel guide). Lexi: 90/90-14 and 100/90-14 - big for a Yamaha, smaller than the SH Mode’s front.
Weight and seat
Lexi: 118 kg, seat 768 mm. SH Mode: 116 kg, seat 765 mm - the two closest premium-lite matches in our verified tables, with the lowest seats in the premium bracket (seat-height comparison).
Equipment
Lexi: front ABS, VVA, 3-year/30,000 km warranty. SH Mode: 18.5-litre underseat bay, ABS on the Sport/Special/Premium versions (our ABS guide). Storage: the SH Mode’s published bay is larger than what the Lexi’s page publishes.
Price - the story of this comparison
Yamaha listed the Lexi from 48,500,000 VND. Honda listed the SH Mode from 66,361,091 VND. Nearly 18 million dong buys the Honda badge, the 16-inch front wheel and the SH family’s resale strength; the Lexi buys more engine, ABS and modern equipment for materially less money. Our verified price table has the full bracket.
Verdict
SH Mode for badge, resale and the big front wheel; Lexi for value, capacity and comfort hardware. Neither is price-published at Nguyen Tu - contact us to confirm current availability.
