The concept of the 2015 RC213V continues the 2014 project of mass centralization with the improvements of each part of the machine. Honda’s concept of mass centralization aims to produce a machine with optimized handling characteristics combining stability, agility, resistance to wheelies and maximum cornering grip.
For 2015 the chassis has been modified in its rigidity balance and designed to reach the maximum compatibility between turning and stability. The twin-spar aluminium chassis is immensely light and yet provides the ideal stiffness and strength characteristics required to contain and deliver more than 175kw (235bhp) from the RC213V’s engine to the rear tyre. As well as strength, the chassis features the right amount of carefully designed flexibility to enhance tyre grip.
We adopted 4 cylinder “V” engine with 1,000 capacity to RC213V which can exploit maximum power of 1,000cc keeping duration for 18 races in season with 5 engines.
We have reviewed all the details of the new engine, making it lighter and reducing friction. We also achieved better fuel consumption than the RC212V whilst retaining more power after 2,000km of durability testing.
For 2015 the RC213V is fitted with Ohlins suspension front and rear. Providing the essential link between wheel and chassis, the suspension’s job is to keep the tyre in contact with the ground and producing maximum grip as the machine hits the thousands of bumps and ripples encountered on every lap. It’s a crucial link in the performance chain and for this reason both Repsol Honda riders have a dedicated Ohlins technician assigned to him.
The lightweight carbon-fibre bodywork plays an important role in making the RC213V as aerodynamic as possible. The 2015 RC213V has a modified fairing to reach the maximum compatibility and performance between handling and drag.
MotoGP tyres are supplied exclusively by Bridgestone. Each rider is permitted to use a maximum of 21 slick tyres during each grand prix weekend and 12 wet tyres. Each grand prix weekend, Bridgestone’s slick tyres are available in two or three compounds and the wet tyres available in two compounds, selected by Bridgestone in advance. The tyre sizes are: Front tyre size: 125/60R16.5 Rear tyre size: 190/65R16.5
Carbon fiber front brakes are provided by Brembo. Carbon brakes work best when they’re hot and reach anything up to 400 degrees C. For rear disk and front disk under wet conditions the RC213V relies on Yutaka steel brake disks.
