2015 Honda CBR500R
For riders looking to move up from a 125, the 2015 Honda CBR500R provides an excellent first big sports bike experience, which will also appeal to experienced riders looking for a great value alternative to larger sports bikes. The fully faired twin-cylinder motorcycle is part of a family of motorcycles from Honda that includes the naked CB500F and adventure sports CB500X. Sharing a common frame and engine, the three machines each have a distinct feel and character and feature a riding position and design that is tailored for, and will appeal to a wide variety of riders, with adaptable abilities that cover a range of uses from commuting and sports, to touring.
The CBR500R’s DOHC, 8-valve liquid-cooled parallel twin layout was chosen because of its light weight, all-round ability and flexible usability. Bore and stroke is set at 67mm x 66.8mm; the crankshaft pins are phased at 180° and a primary couple-balancer sits behind the cylinders, close to the bike’s centre of gravity. The primary and balancer gears use scissor gears, reducing noise. The crank counterweight is specifically shaped for couple-balance and its light weight allows the engine to spin freely, with reduced inertia. PGM-FI fuel injection provides superb throttle response and peak power of 47hp arrives at 8,500rpm, with 43Nm torque delivered at 7,000rpm.
The ‘triangle’ proportion of crankshaft, main shaft and countershaft is very similar to that of Honda’s four-cylinder RR engines, making for a very compact unit. The six-speed gearbox also mirrors that of its RR cousins, allowing for a short engine and uses the same gear change arm structure and link mechanism. A deep sump reduces oil movement under hard cornering and braking.
The CBR500R’s 35mm diameter steel diamond-tube mainframe is light and strong, and has a tuned degree of yield that gives plenty of feedback to the rider as road surfaces change. The shape and position of the engine mounts, and the frame’s rigidity balance, have also been carefully balanced to reduce vibration. Wheelbase is 1410mm and rake and trail are set at 25.5°/102mm giving nimble, yet reassuring steering. Mass centralisation, with the engine in very close proximity to the swingarm pivot point, delivers turning agility and optimum front/rear weight distribution ensures stability. Kerb weight is 194kg. Seat height is low at 785mm, making the CBR500R very easy to manage and its sporty riding position will comfortably accommodate riders of varying heights thanks to a relatively high handlebar position.
The 41mm telescopic front fork, with 120mm stroke, delivers a compliant yet controlled ride and gives a great connection to the front tyre. Pro-Link monoshock rear suspension features optimised leverage ratios and 9-stage preload adjustment for the rear shock. It works with a rigid swingarm, constructed from 70mm x 30mm box-section steel. Final drive is via 520 sealed chain.
Lightweight, 17″ cast aluminium wheels employ hollow cross-section Y-shaped spokes. Front wheel width is 3.5inch with a 120/70-ZR17 tyre, the rear 4.5inch and 160/60-ZR17 tyre. A single front 320mm wavy disc and two-piston brake caliper is matched to a 240mm rear disc and single-piston caliper. ABS is fitted as standard.
The comprehensive dash features a digital speedometer, digital bar graph tachometer, odometer, dual trip meters, clock, plus digital fuel level gauge and fuel consumption. HISS (Honda Intelligent Security System) is built in to the ignition, and the headlights feature two 55W H7 Halogen bulbs and multi-reflectors. There is space under the seat to store a U-lock.
