The Yamaha MT-15 packs the same engine as its faired cousin, the YZF-R15. This gives it a distinct power advantage over the baby Duke, and it shows. In terms of 0-60kmph runs, the MT is 1.44 seconds faster than the 125 Duke. When it comes to 0-100kmph runs, the performance gap is further demonstrated, with the Duke lagging behind the MT by more than 5 seconds!

Both motorcycles are street-friendly, urban-focused machines and both motorcycles do a decent job of carrying out swift overtaking manoeuvres and zipping past traffic. However, thanks to its 14.7Nm of torque, the MT-15 is quicker in both 30-70kmph and 40-80kmph roll-ons. Not to mention, with the added benefit of VVA, the MT also gets a decent amount of low-end grunt without compromising on top-end performance, thus making it perfect for city runabouts.

Both the Yamaha MT-15 and the KTM 125 Duke get single-channel ABS as standard. Even the braking hardware is closely matched, which is shown in the numbers above. However, it is the MT that offers better bite, lever feel and progression. Even the ABS intervention on the two is quite different, as explained by the numbers.

A smaller capacity engine should result in better fuel efficiency, right? Well, that’s not the case here. The Yamaha MT-15 is more frugal than the 125 Duke in the city. This is due to the fact that the KTM’s engine requires to be revved in order to extract any sort of performance, which is sure to dampen its efficiency. Thanks to Variable Valve Timing, you don’t have to compromise on low to mid-range performance for top-end performance in the MT15. Even the engine remains stress-free in most cases, thus enhancing fuel efficiency.
