Radical in design, radical in technology and performance. Based on the YZF-R1. The MT-10 is the outspoken top of the MT range. Let’s have a look at some of the key questions that our engineers and planners had to face.
How much of R1 is in the MT-10?
The MT-10 is built on the same engine/chassis platform as the R1, benefitting from its latest technology. However, it is not “a naked R1”. Its character is significantly changed:
Instead of focusing on race performance and race speeds (up to 300 kmh), the MT-10 has its focus purely on street riding emotions. At useable, public-road speeds.
Did this influence the use of technologies?
The R1 is built for very high rpm ranges at top speed, with full use of expensive materials and technologies to enable that: Titanium conrods and valves, YCC-I variable intake, dual fuel injection…
For MT-10 these were not necessary. Instead, the engine is tuned for torque and for a more emotional response at low and mid rpm:
- Maximum torque comes in at much lower rpm
- The torque curve is higher on most of the rpm range
- Maximum rpm is lower. All this is done by different valves, cam profile, pistons, combustion chamber shape and fuel injection settings. And for even more responsiveness, the final drive ratio is shortened!
How is the MT-10 engine explosive but controllable at the same time?
To handle the higher torque, the crankshaft has an increased inertia. And what’s more important, the special “crossplane crankshaft” technology creates a great feeling between rider and engine.
A conventional 4-cylinder engine has a regular firing order, with a combustion at each 180 degrees of crankshaft rotation. With this construction, pistons and conrods are rising and falling in pairs: The outer pistons together and the inner pistons together. But that causes inertia fluctuations that interfere with the pure combustion torque developed by the engine.
On the crossplane crankshaft, pistons rise and fall alone, meaning their inertia fluctuations are spread out and the rider has an unspoilt and more immediate connection to the combustion torque of the engine. It is easier to exploit the engine’s output this way.
This technology was originally developed for our MotoGP bikes, with input from Valentino Rossi!
The resulting firing interval is irregular (at 270° - 180° - 90° - 180°). Giving a special character to the engine, with a deeper and throaty sound.
Our Project Leader Shuichi Mori states: “The crossplane engine is a fantastic experience but until now this was only available for supersports riders. With the MT-10 we are proud that we can bring this special Yamaha technology to a wider range of customers.”
How is MT-10 agile and stable at the same time?
This starts with the wheelbase that is an ultra-short 1400 mm for fantastic handling.
-The fantastic aluminium Deltabox frame and swingarm are adopted from R1: a compact, light and rigid construction. For MT-10 it is finetuned in its strength-rigidity balance.
- The riding position is slightly moved forward for an ideal weight distribution.
- As on R1, there’s an electronic steering damper on board.
- Tyres are a special Bridgestone Battlax Hypersport S20 version.
- The Assist & slipper clutch provides lighter operation and slipper function when downshifting for corners.
- Suspensions are the remarkably high-grade and sensitive KYB units, same as on R1 but with different setting:
- Front 43mm USD fork, cartridge type, adjustable in preload, compression and rebound damping.
- Rear monocross link suspension, adjustable in preload, low-and high-speed compression damping and in rebound damping.
Is there any versatility in such a radical bike?
The front face with its menacing look and the extreme specs of the bike may fool you.
Product planning manager Oliver Grill says: “Behind its aggressive attitude, is a cleverly engineered bike that is more than just a naked supersports. It combines R1 DNA with Tracer-like versatility in a very unique way.”
- The riding position is active and upright, with a wide handlebar and a slight forward lean; well integrated with the machine.
- The seat is wide and allows freedom to move; a hip stopper enhances you firm grip on the bike during acceleration.
- Despite its naked streetfighter design, the small front mask is quite effective in deflecting the wind from the upper body! It is frame-mounted to keep a light and unobstructed steering feel. And with the accessory windshield the protection level is on pair with that of the Tracer 900.
- The short, minimalistic tail has mounting points for accessory side bags – good for weekend trips.
- Cruise control is standard equipment for that extra convenience in speed-controlled situations.
What explains the price difference with R1?
MT-10 is kept as efficient and essential as possible. As we’ve seen above, the special items to enable very high rpm for top speed were not necessary. Also the riding feeling is kept very pure: no abundance of electronic control systems. Finally, exclusive items like the magnesium wheels and engine covers were replaced by aluminium.
Which other features are on the bike?
- Traction Control System (3 levels to choose from, plus off)
- D-mode to set the engine response (3 levels to choose from)
- Aluminium handle crowns with tapered aluminium handlebar
- Lightweight titanium muffler (exhaust pipes are stainless steel)
- Dry weight of only 190 kg
- Dual, 320mm front discs with 4-pot, radial-mounted calipers and sintered brake pads
- Supersports spec brakes and ABS
- All-LED lights, front lights very powerful
- LCD instrument panel with shift light, gear position indicator, clock, outside temperature, fuel consumption information and lots more
- DC outlet as standard equipment.
