Yamaha YZF 250- R4


Yamaha is going to surprise all of us by launching a 250cc bike on R1 platform at the upcoming Delhi Auto Expo if we believe the photograph. To our surprise the bike is called R4 with 250cc engine though ideally it should be R2 or R250 but in any case if it is true that Yamaha is ready to compete (and probably going to win) with Kawasaki in 250cc true sports class, then it really doesn’t matter by what name it is going to be launched, isn’t it?

However Yamaha India have not commented on this but we can expect some surprise as committed earlier by the company’s top officials. Coming to the bike it looks like it is a combination of R1 and R6 and I have a gut feeling that if this bike is ever launched in India it will certainly take lead over Kawasaki Ninja 250R, if priced prudently by Yamaha. What are your opinion guys?

Yamaha YZF-R1 2010

2010 Yamaha YZF-R1

Introducing the 2010 R1 … Yamaha's technical "Tour de Force."

The MotoGP-inspired R1 is the most advanced Open-class production motorcycle.

The R1 has been designed to be the "Ultimate Cornering Master" of the open super sport class and one of the keys to incredible handling lies partly in the chassis but equally as important, in its ability to put useable power to the ground. This revolutionary cross-plane crank R1 delivers as much power as the rider wants, exactly when the rider wants it … by a simple twist of the right wrist; leaving the rider feeling like they are directly connected to the rear wheel of the new R1.

Forget everything you ever knew about the supersport liter class. The 2010 Yamaha YZF-R1 is unlike anything before. That's because it's the world's first production motorcycle with a crossplane crankshaft. The result? Incredibly smooth power delivery and outrageous torque for a rush like you've never experienced.

The 2010 Yamaha R1 represents a paradigm shift in technology, performance and controllability among litre class sport bikes. Inspired by Yamaha's M1 MotoGP race bike, this latest generation R1 features a crossplane crankshaft design with an uneven firing order to provide outstanding yet easy to control torque and an exceptionally linear throttle feel never experienced before. But there is far more to the R1 than just a revolutionary engine.

2010 Yamaha YZF-R1

Features and Benefits (USA):

Key Features:

" The YZF-R1 garnered the prestigious award as the 2009 Motorcycle of the Year from Motorcyclist Magazine. The YZF-R1 was chosen for its MotoGP®-inspired engine and chassis technology, and for its luxurious fit and finish.

" Back for 2010, the YZF-R1 is the only production motorcycle with a crossplane crankshaft. Crossplane technology, first pioneered in MotoGP® racing with the M1, puts each piston 90° from the next, with an uneven firing interval of 270°- 180°- 90°- 180°. This uneven order does an amazing thing… it actually lets power build more smoothly. That means smooth roll-on delivery out of the corners, with outstanding tractability, followed by very strong high rpm power. It's a feeling that's simply unmatched, like having two engines in one: the low-rpm torquey feel of a twin with the raw, high rpm power of an inline four. This breakthrough technology on the YZF-R1 represents a paradigm shift in both technology and performance.

" This R1 keeps all the technological superiorities developed for its predecessor: YCC-T™ (Yamaha Chip Controlled Throttle) is MotoGP® inspired fly-by-wire technology used to deliver instant throttle response. YCC-I® is Yamaha Chip Controlled Intake which is a variable intake system that broadens the spread of power. The fuel injection system provides optimum air/fuel mixtures for maximum power and smooth throttle response.

" The R1 features Yamaha D-MODE (or drive mode) with rider-selectable throttle control maps to program YCC-T performance characteristics for riding conditions. The standard map is designed for optimum overall performance. The "A" mode lets the rider enjoy sportier engine response in the low- to mid-speed range, and the "B" mode offers response that is somewhat less sharp for riding situations that require especially sensitive throttle operation. Switching maps is as easy as pushing a button on the handlebar switch.

" In keeping with this machine's exceptional cornering ability and crisp handling, the aluminum frame has been designed to offer exceptional rigidity balance. The rear frame is lightweight Controlled-Fill die-cast magnesium, contributing the optimum mass centralization. Suspension includes SOQI front forks which use one of the tricks developed for our winning MotoGP® bikes: independent damping. The left fork handles compression damping and the right side handles the rebound damping. And the rear shock adopts bottom linkage for optimum suspension characteristics.

" The bodywork does more than add break-away-from-the-crowd styling with its more serious, less busy look. The side fairing is smooth for a sleek appearance. And, instead of the usual four-bulb headlight design, the R1 has only two projector-type bulbs mounted closer to the nose of the bike. This positions ram air ducts closer in for a more compact, smooth look. In addition, the rounded lenses are unique to the supersport industry.
