The PG-1 and the CT125 attack the same idea from opposite directions: light motorcycles that survive bad roads while staying practical in the city. Yamaha builds the PG-1 as a semi-automatic adventure underbone; Honda builds the CT125 as a manual-clutch trail Cub. All figures are from the official Yamaha VN PG-1 2026 page and Honda VN CT125 page (retrieved 23-24 September 2026).
Engines and gears
| Yamaha PG-1 | Honda CT125 | |
|---|---|---|
| Engine | 113.7 cc air-cooled, SOHC 2-valve | 123.9 cc air-cooled |
| Power | 6.6 kW @ 7,000 rpm | 6.76 kW @ 6,250 rpm |
| Torque | 9.5 Nm @ 5,500 rpm | 10.9 Nm @ 4,750 rpm |
| Gearbox | 4-speed, automatic centrifugal clutch | 4-speed manual clutch |
| Claimed economy | 1.76 L/100 km (spec table) | 1.61 L/100 km |
The CT125 makes its torque lower and pulls harder from rest; the PG-1 asks nothing of your left hand. That gearbox difference is the real decision: clutch-and-lever (CT125) or foot-shift-only (PG-1).
The adventure numbers
The PG-1’s party piece is 190 mm of ground clearance on 16-inch block-pattern 90/100-16 tubed tyres. The CT125 rides 17-inch rubber (80/90-17 front and rear) with rugged trail styling; Honda does not publish its clearance figure on the retrieved page, but the two bikes fill the same niche with different geometry — the PG-1 stands taller and narrower.
Weight, size and price
The PG-1 lists 107 kg with a 795 mm seat, 1,280 mm wheelbase and a 5.1 L tank. The CT125 is heavier at 117 kg, with an 800 mm seat, a 5.4 L tank and a list price of 85,997,455 VND. Yamaha’s retrieved PG-1 page does not display the current retail price, so check Yamaha Vietnam or a dealer for the live figure. Honda’s CT125 is roughly double the price of a normal underbone; the PG-1 slots into the market below it.
Which one
Choose the PG-1 for clutchless simplicity, flood-season clearance and a lower entry price; choose the CT125 for the manual-clutch experience, Honda Cub durability culture and a longer-travel all-rounder. Riders who want the same tall clearance without any trail styling are not served by either — and riders cross-shopping the CT125 against its classic sibling should also read our CT125 versus Super Cub C125 comparison.
