Below 155 cc, speed is really a power-to-weight question. Yamaha and Honda publish both numbers for every current model (retrieved 23 September 2026) - so the ranking below is the manufacturers’ own arithmetic, no estimates.

The verified power ladder

Rank Model Max power Kerb weight Power per 100 kg
1 Yamaha Exciter 155 VVA 13.2 kW @ 9,500 rpm 123 kg wet ~10.7 kW
2 Honda CBR150R 12.6 kW @ 9,000 rpm 139 kg ~9.1 kW
3 Honda Winner R 11.5 kW @ 9,000 rpm 124 kg ~9.3 kW
4 Honda Super Cub C125 6.87 kW @ 7,500 rpm 109 kg ~6.3 kW
5 Honda Future 125 FI 6.83 kW @ 7,500 rpm 104 kg ~6.6 kW
6 Honda CT125 6.76 kW @ 6,250 rpm 117 kg ~5.8 kW
7 Honda Wave RSX 6.46 kW @ 7,500 rpm 98 kg ~6.6 kW

The Exciter 155 VVA tops the class on both absolute power and power-to-weight, helped by its four-valve, VVA, liquid-cooled head. The Winner R actually edges the CBR150R on power-to-weight; the CBR counters with fairing and the 12-litre tank for high-speed touring.

What power figures do and do not say

Peak power arrives at high revs (9,000-9,500 rpm on all three sport models). None of these bikes will feel fast below half throttle - that is what the manual clutch and gearing are for. Claimed fuel economy tells the other story: the Exciter’s 2.07 L/100 km is the best of the three sport bikes.

More speed, more licence responsibility - check what the A1 licence covers before you buy. And remember real-world economy and performance vary with load, speed and conditions.
