Yamaha YZF-R15 "What's next"

Yamaha Racing Corporation, Japan who in turn authorized Daytona corporation,Japan to make specialized go-faster bits for Yamaha's YZF R15.

The racing kit includes the following

• Re-mapped ECU
• High-lift cam-shaft
• Full exhaust system
• Special alloy sprockets
• Adjustable Foot rests
• Larger diameter petal disc front brake
• Stainless steel brake hose
• Race-spec master brake oil cylinder

Re-mapped ECU

The rev-limiter has been moved further and instead of 9,800rpm cut-in point of the stock ECU, the race-prepped ECU kicks-in only after the rev-counter needle breezes past the 12,800rpm mark.Yamaha has developed this special ECU which is tuned and mapped to suit the other performance upgrades that come in the package.However, the ECU has been configured with a prefixed map canceling out the great opportunity of allowing the end-user to program it according to his own liking and needs.


High-lift Camshaft

The package also consists of a high-lift cam which provides better flow of air-fuel mixture by getting the valve further out of the way than stock. The altered ECU further smooths out the extra power produced by the engine and does not put strain on the valvetrain.


Full exhaust system



This one will be a big seller. Loud, throaty and adds instant punch to the bike. The full exhaust system is a bolt-on part and immediately improves low-end torque and power delivery.


Duralumin Special Alloy Sprockets



There are two options for the rear sprockets with 40 teeth and 42 teeth, made out of lightweight special alloy called Duralumin. The product line-up will include multiple sprocket options depending upon the demand and need of the rider.


Brake upgrades


A 296mm diameter petal disc upfront coupled with a stainless steel braided brake hose, put the R15's brakes into a different league altogether. Braking has improved significantly and good response under hard-braking and mid-corner speed-shedding,Braking times and distances has dropped by a big margin over the stock bike.
The kit also includes a MotoGP race-bike style master brake oil cylinder. The improved power and braking demands stickier rubber though than the stock tyres can deliver and this is a sore spot worthy of being treated. Exactly a year ago, many were stunned with the performance of the tyres employed on the R15 and were raving mad about them. However, the stock tyres now seem to be struggling to cope with the added horses.

Quick throttle


The package also includes a racing quick throttle that reduces the total travel angle of the throttle from the stock bike's 90 degrees to 60 degrees. The quick throttle helps in reducing throttle actuation time and provides quicker response from the bike with minimal movement of the wrist.

Rear set footrests




Apart from the performance boosting bits to the drivetrain, Yamaha have thoughtfully provided one very critical upgrade to the bike which is exquisitely crafted rear set footrests. This positional placement of foot rest with allied linkages perfectly optimized for gear shifter and rear brake pedal is most welcome and highly recommended. It is three-way adjustable depending on rider preference and comfort.

The entire kit works in perfect harmony as the high-lift cam, ECU, the exhaust and the sprockets all have been tuned to work together to give the best possible performance. All of this sincerely satisfies the needs of a serious track-enthusiast or the newbie racer. To match the go, Yamaha is also offering an HID headlight kit for that added bling factor!

Yamaha still hasn't disclosed the pricing of these parts or the full kit as they are yet to determine the exact costs, since the parts will be imported directly from Daytona (the firm) in Japan. Yamaha will start taking orders from July for these parts by email and via their website.
