We attended the South African launch of the 2015 Yamaha R1. Watch as journalist Wilhelm Lutjeharms explains the highlights of the new bike, and takes it around Killarney Raceway.

Full riding impression and all the specifications of the R1 and R1M:

KILLARNEY RACEWAY, Cape Town – Any superbike launch day corresponds with a high level of anticipation and the recent R1 launch was no different. Although Yamaha has a comprehensive range of products on offer it’s the top-of-the range superbike that represents the pinnacle of the company’s current level of technology and engineering prowess.

In the company of segment rivals like the new BMW S 1000 RR, Yamaha would have been under pressure to release something special, and it did.

Highlights
The 998 cc engine features titanium fracture-split connecting rods together with the signature Yamaha cross-plane crankshaft setup.
To lower overall weight magnesium has been adopted for both the wheels and subframe. There is also an aluminium fuel tank, a rarity on motorcycles. The result of these lightweight measures is a 6,8 kg reduction in overall mass.

The previous generation R1 will always be remembered for how wide it was. This has been addressed with the new model. Looking at the bike head on you instantly note a narrower design, made possible by the slimmer engine block.

The aerodynamic setup of the bike has also been improved by 8% compared to the old bike. This is visible everywhere. From the smooth (race-bike inspired) nose, to the hollow tail piece featuring small fins.

The electronic package is another significant highlight. The ABS braking system features a unified setup activating both the front and rear brake simultaneously. And no, it cannot be deactivated. Yamaha’s six-axis inertial measurement unit is connected to both gyro- and g-sensors to measure pitch, roll, yaw and acceleration in fore, aft, up and down, and left and right positions.

On-board a clear and colourful screen gives the rider access to Yamaha’s ride control system. Here settings for the traction-, slide-, lift- and launch control systems can be selected. There are also four different throttle mappings to choose from.

The R1M
The R1M is step up from the Yamaha R1. Your additional R100 000 (over the R1’s R230 000 price tag) gains you several carbon-fibre parts, an Öhlins electronic racing suspension and a communication control unit (a data logging system that enables the rider to capture ride data and then download it via WiFi).

Visually, the R1M also has a clear-coated brushed aluminium fuel tank and a brushed aluminium swing arm.
