Review

Yamaha YZF-R15 Review Small-displacement sportbikes are getting more attention because the world financial system continues to struggle. The 150cc Yamaha YZF-R15 was the first sportbike produced in India back in 2008, and the gas-injected model now receives a host of upgrades and is obtainable to the Australian, New Zealand and Colombian markets.

Yamaha’s YZF-R15 has supplied riders the ultimate sportbike in its 150cc segment, managing to retain the unadulterated feel of its legendary mentors, the supersports YZF-R6 and R1.

Leaned over mid-corner, tires fiercely gripping the tarmac, its engine screaming out the excessive revs it craves, this Yamaha has treated aspiring sportbike riders ever since its launch. The lean and compact, know-how-packed R15 represents a mean package, accelerating, turning and stopping with the aggression of a precision, laser-guided missile.

Powering around a set of corners at the Madras Motorsports monitor, India, the YZF-R15 Model 2.0 feels every bit pretty much as good as Yamaha’s “Racing Instinct” philosophy suggests. Simply how a lot better is the R15 V2.0, and might it reignite the fervour amongst sport bikers as did the unique?

The listing of adjustments is extensive. Though the aggressive twin-headlights remain acquainted, there’s a beefier mid-fairing region, now with slotted vents that Yamaha claim enhance the bike’s aerodynamic effectivity by 4 percent. A stylish new mock carbon fiber panel appears part of the body, whereas V 2.0 also boasts an extensively altered, steeply angled and waspish looking split-seat. On the rear you see the next, YZF-R6 inspired LED tail-lamp. Under this sits a smartly machined, alloy number plate and switch indicator mount. The exhaust is far better wanting, extra aggressively angled and you can’t miss the flowery new rear wheel hugger which doesn’t really fit in nicely on a sportbike like this.

Look nearer and finer adjustments are obvious; the still compact R15 trying longer than its predecessor, as its wheelbase has extended 55mm (almost 2 inches), because of a brand new alloy swingarm, rare for this class of motorcycle. A larger 130/70 part radial rear tire completes the muscular looking rear. The front disc brake enjoys a larger service, whereas the rear disc is now slightly larger at 220mm.

The ECU has modified tuning for improved throttle response, and the throttle working cam is formed for extra linear response. Yamaha has sadly failed so as to add power to the brand new model, and lovers are positive to feel let down when noticing the unchanged 16.eight hp at 8500 rpm peak power output. What’s extra, the V2.zero suggestions the scales at 5kg (eleven lbs) more than the original R15. It now claims a 300-pound curb weight.

Sling a leg over the YZF-R15 V2.0, and you immediately understand how the driving position is so much extra observe focused, with its relatively ahead-set stance. A light-weight, unobtrusive buzz from the 150cc, liquid-cooled, single-cylinder powerplant is acquainted as I make my method around the observe on a cautious initial lap.

What’s instantly apparent is how the ability ship has improved. Not like earlier R15’s that had to be wound up to actually get going, the V2.0 is clearly extra responsive, with a healthier punch within the bottom and mid-range of its powerband. The bike revs cleanly to its 10,000-rpm limiter. This extra consumer-friendly nature vastly improves the R15’s public street talents, which was a sore level on the earlier motorcycle. As speeds enhance, it’s clear that fears of any vital drop in performance are unfounded. Pleasantly, our assessments confirm the brand new Yamaha as sooner, the V2.zero achieving a hundred kph (62.5 mph) from standstill half a second quicker than managed by us on the older motorcycle, in 14.14 seconds.

Yamaha’s metal Deltabox body is the magic wand that grants the R15 rock-stable poise around corners, and an virtually feline-like affinity for fast route changes. It’s a case of the best getting higher, the longer alloy swingarm and improved tires considerably improving stability. An enormous change is palpable when attacking corners, with some negligible sacrifice to flickability, however a newfound stability there for the asking in a corner. The R15 V2.0 is extra forgiving, and prods you to trip harder and faster. The sportier driving place and heavier entrance weight bias provide a extra connected, direct really feel, which skilled riders will exploit to extract better pace. The revised, Indian-made MRF tires present solid grip when leaned over or beneath hard braking. We found nothing but absolute commitment even when anticipating rear wheel hop whereas pushing arduous over patchy, bumpy tarmac. The chunk from the front brake is difficult to fault, at all times highly effective sufficient, while nonetheless progressive.

Street riders have handled the R15’s shortcomings earlier than, and so have only about as much to complain about, with the bonus of improved power supply making an attempt to make up in some measure for the uncomfortable riding position.

Paying more for this upgraded model regardless of no peak energy gains are might sound to hold again this revised mannequin, and the R15’s good chassis actually begs for extra power to match its perfectly sorted dynamics. The competition is just intensifying with every passing day, which means Yamaha nonetheless need to drag their gloves off somewhat further, with much more conviction.
