2015 Yamaha R1 and R1M Specs and Details – Yamaha wasn’t going to be outdone this year on their home turf, the racetrack, by some little supercharged Ninja. All-new for 2015 is the Yamaha R1 and the never-before built Yamaha R1M. THIS is Yamaha’s 2015 R1, with more power, less weight and a sophisticated new electronics package.
The new version of the flagship sports bike makes a claimed 200hp and weighs 199kg wet, 18hp more and 7kg less than the current model. It gives the new R1 a power-to-weight ratio of more than 1hp/kg and one of the best available in any bike on the market.
It’s got a new crossplane engine with titanium fracture-split conrods, a 10.5-litre airbox, two-directional fuel injectors and a titanium exhaust. 2015 Yamaha R1 and R1M Specs
Highlights of the new eletronics package include banking-sensitive traction control and ABS, launch and lift control, power modes and a quick-shifter. A modified chassis features an asymetrical aluminium deltabox for compact dimensions and a short wheel-base. It’s got a magnesium sub-frame, aluminium tank and cast magnesium wheels.
The fairing design is influenced by Yamaha’s M1 MotoGP bike with a central ram air take, according to the firm. Yamaha also unveiled a higher-spec limited edition called the R1M, with Ohlins Electronic Racing Suspension, a data-logging system with integrated GPS, and the capability to upload new settings from a mobile phone or connect wirelessly to a tablet. 2015 Yamaha R1 and R1M Specs and Details
Both bikes were revealed at a press conference in Milan tonight by MotoGP legends Valentino Rossi and Jorge Lorenzo, who acted as development riders on the project. The machines are due to be shown at this week’s Eicma Milan motorcycle show.
The new YZF-R1 will cost around £15,500 when it comes to the UK in March next year. The R1M will cost roughly £20,000.
2015 Yamaha R1 and R1M Specs
Yamaha wasn’t going to be outdone this year on their home turf, the racetrack, by some little supercharged Ninja. All-new for 2015 is the Yamaha R1 and the never-before built Yamaha R1M.
Both bikes will feature the same basic components and the signature 1,000cc cross plane engine. Designed for the racetrack, covered in carbon-fiber fairings, the R1M still retains mirrors, tag mount and even a snap-on rear seat and peg mounts. “The R1M blurs the line between a Moto GP bike and a production bike,” said Aaron Bast, Senior Product Planner at Yamaha
The first R1 was intended to be a great road worthy sportbike. “But that changed this bike was designed as a race bike first and foremost,” said Aaron.
The R1 hits the scales at 439 pounds wet, 15 pounds lighter than last year’s model. The R1M, despite having its carbon fiber fairings, weighs in slightly heavier at 443 pounds. That’s primarily due to the added suspension electronics and data logging electronics. The wheelbase is almost half of an inch longer than last year’s, at 55.7 inches.
While Yamaha is sticking with its signature crossplane crankshaft engine design, this is an all-new engine with more compression, 13:1 over the 12.7:1 compression from last year’s model, 45mm throttle bodies, lighter forged pistons and larger valves.
Yamaha wanted to run different cams so they coated the rocker arms in diamond-like carbon coating to withstand more aggressive lobes.
The aluminum Delta box frame is all new, but overall the chassis is similar to the previous generation. “From the very beginning our engineers were able to start from scratch,” said Aaron. “We built a level of motorcycle that, up until now, only factory riders could experience.”
The new blue magnesium wheels save two pounds front and rear. The subframe is also made from magnesium. Another big weight saver is the aluminum gas tank, which saved a whopping 3.5 pounds over the steel tank.
he bore went up and the stroke down, making the engine an even more oversquare bore engine:
2014 R1 – 52.2mm Stroke X 78mm Bore
2015 R1/R1M – 50.9mm Stroke X 79mm Bore
The shorter stroke reduces piston speed and offset cylinders greatly take stress away from the rotating assembly. Lighter weight pistons, off-set cylinders, fraction-split titanium connecting rods (first time ever on a motorcycle) are all factors that basically mean there is far less stress being applied to the pistons. Less stress means a longer life, better able to withstand to upgrades and more efficiency.
Yamaha lost nine pounds in the block thanks to magnesium oil pan, valve and side covers. 2015 Yamaha R1 and R1M Specs and Details
R1 Vs. R1M
The R1 and R1M have the same basic engine, although there’s been no confirmation on the power differences; the major difference in money comes from the suspension and electronics.
The R1M will feature 43mm Öhlins electronic suspension with 4.7 inches of travel and Öhlins electronic suspension single shock with a piggyback reservoir in the rear.
The R1 will feature 43mm KYB® forks up from and a KYB® Single shock with piggyback reservoir in the rear. Both bikes will have 4.7 inches of travel but the R1M will have a slightly higher seat height at 33.9 inches.
The R1 is projected to make north of 190hp at the crank, but that’s not confirmed from Yamaha. We’re hoping the R1M will make more power, but if it does it’ll more than likely be due to exhaust and intake, possibly different cams. The overall engine design is the same between the two
Adaptive Slide Control
This is a first for a production motorcycle. Yamaha took it straight from the 2012 YZR-M1 race bike. It’ll slightly cut power when it feels the bike is greatly leaned over and the rear tire slides.
Adaptive Lift Control
We know this as wheelie control; luckily it too can be turned off.
Adaptive Launch Control
A rarity on any bike, the launch control will limit rpms to 10,000 and again can be adjusted depending on the conditions from the slick mode to rain mode.
This will blip the throttle for just an instant to allow for quicker shifts without backing off the gas.
Track Developed ABS
The integrated ABS will work both brakes even if only one is applied. It has includes lean-angle ABS which will send a different, unique signal to actuate the ABS signal to the brakes when the bike is leaned over; this will keep the bike leaned over even if you grab the brakes hard.
