Yamaha R15 V4 vs MT-15 V2: clip-ons against a bar, now against later

There are comparisons where the two machines disagree about everything, and there are comparisons like this one, where Yamaha sells the same engine, the same frame architecture and the same 155cc argument twice — once with clip-ons and a fairing, once with a bar — and then adds a twist neither of the others has: the MT-15 V2 is still a projection. The R15 V4 is in showrooms; the MT-15 V2 is listed here for late 2026 with figures carried forward from the outgoing model. That asymmetry shapes every paragraph below.

One cylinder, written twice

The 155cc VVA single is the best-justified engine in Indian entry-sporting. Peak power arrives at 10,000 rpm and the unit genuinely enjoys the last quarter of the tacho, which means both bikes ask you to use the six-speed box the way a torquey commuter never requires. Out of a corner, the R15 pulls to its 140 km/h ceiling with aerodynamics helping; the MT’s projected 130 is a fair read of what a naked front end costs at speed. The torque figures — 14.2 Nm and a provisional 14.1 — confirm what a lap says anyway: these are the same motorcycle wearing different amounts of plastic.

If the update lands with the equipment Yamaha has quietly been preparing on the R15 M — quickshifter, traction control, connectivity — the MT becomes the stronger everyday case for the same money. That conditional is the entire suspense of this comparison, and no one should pretend otherwise.

Where the bar beats the clip-ons

In traffic the MT’s advantage is not theoretical. An aluminium handlebar instead of clip-ons means the wrists are neutral rather than loaded, the levers are less strained at a jammed signal, and looking over a shoulder to change lanes is a neck movement rather than a lean. The projected 139 kg undercuts the R15’s 142, and 170 mm of ground clearance against 165 buys confidence over a breaker the R15’s pegs would report.

The R15’s counter is the thing Yamaha builds it for. The upside-down fork, the die-cast aluminium swingarm and the trellis-derived frame make it the most composed mid-corner chassis at 155cc sold in this country — the reference point every rival is described against. On a track day or an empty ghat section, the clip-ons put weight on the front brake in a way a bar never will, and the fairing lets the rider sit inside the air at 120 km/h instead of fighting it.

The honest summary: the R15 is the better motorcycle for the twelve corners a month you actually attack; the MT is the better motorcycle for the three hundred commutes.

Living with either

The R15’s compromises are the track-biased contract: high pegs that kiss a speed breaker when loaded, a rear end that reports broken tarmac directly to the pillion, and a split seat that is token as a passenger arrangement. Owners who ride mostly in traffic test these daily and test the cornering only occasionally.

The MT inherits the engine’s need for gear changes and, on the outgoing evidence, the firm rear suspension that is the segment’s most-criticised trait. What it adds on the projected side is claimed 48 kmpl — six better than the R15’s 42 — which over a 2,000-km month at real-world numbers is the difference between two fills and one-and-a-half. Riders who keep a 155 below 6,000 rpm report mileage comfortably beyond either claim.

Storage, service and resale are a wash: same brand, same dealer network, same consumables, and both hold value well in the used market for as long as the 155s stay the entry drug of choice.

The price, and the date

Yamaha’s projected band puts the naked above the faired bike: ₹1.68-1.76 lakh against the R15’s ₹1.55-1.72. That is not unprecedented — nakeds with premium finish sometimes out-price entry faired trims — but it means the MT has to earn its case on ergonomics and equipment, not money. The R15 V4 at ₹1.55 lakh is simply the cheapest way into this engine, and the R15 M at ₹1.68 lakh carries confirmed electronics that the MT has only been promised.

Timing matters more than the price sheet. A buyer today gets a homologated, rideable, reviewable motorcycle. A buyer who waits gets provisional figures, a launch date this catalogue marks as indicative, and an update that could just as easily arrive with a better console as with the quickshifter.

Which one, and when

Buy the R15 V4 if you want the chassis, the fairing and the confirmed quickshifter package now, or if any part of your riding is at a circuit. It is the sharper instrument and the safer purchase.

Buy the MT-15 V2 — by waiting for it — if your 155 is a traffic motorcycle: the bar, the weight, the projected mileage and, eventually, the R15’s electronics in naked form make it the more adult daily machine, provided Yamaha delivers the projection.

And if neither of those descriptions fits — if the office, the pillion and the budget are what actually decide your purchase — both of these are the wrong segment, and the catalogue’s 160s will thank you for the honesty.
