Honda CBR500R a sporty mid-sized twin

By: IOL Motoring Staff

Johannesburg - Honda has a history of sporty, high-revving parallel twins going back to the 247cc C70 of 1957. They took a back seat in 1968 with the advent of the Honda CB750 Four and its smaller siblings, but never really went away - and now they're back, in the shape of the CBR500R.

It has all the advantages of a parallel twin - a compact, narrow engine with its masses neatly centralised - and, although it has clearly been built down to a budget (steel frame, relatively unsophisticated suspension), Honda has succeeded in giving it a sporty persona with a Fireblade-style full fairing, 17” cast wheels at both ends, digital instrumentation and a seating position that looks a lot more radical than it is.

There's been no budgeteering on the engine, however; it's liquid-cooled, twin-cammed and fuel-injected through four valves per cylinder, almost exactly square at 67 x 66.8mm bore and stroke for a true capacity of 471cc.

In other words: proven, hard-core engineering, exactly what Honda does best.

The spec sheet quotes 35kW at 8500 revs and 43Nm at 7000rpm, delivered via a conventional cable-operated clutch, six-speed 'box and chain final drive - although we're treating its claim of 3.7 litres per 100km with appropriate restraint 'til we've ridden one.

The 35mm diameter steel diamond-tube frame has been tuned in the same way as its bigger stable-mates, for controlled flexing in some planes and none at all in others, matched to a no-nonsense swing-arm welded up from three pieces of 70 x 30mm rectangular steel tubing for a short-coupled 1410mm wheelbase and a fairly conservative (by spoprts-bike standards) 25.5-degree rake angle.

CONVENTIONAL SUSPENSION

Suspension is entrusted to 41mm conventional cartridge forks, devoid of any adjustment, and Honda's signature Pro-Link rear set-up, adjustable only for preload, while the 17” cast rims carry 120 section front and 160 section rear radial tyres.

Kerb weight is a surprising 194kg, about the same as a 600cc supersports four, but a lowish (790mm) seat height, relatively high handlebars and slim midsection make the CBR500R easier to manage.

The brakes are an odd mix: petal discs and ABS rings make them look state-of-the-art but the real work is left to bargain-basement Nissin callipers - a twin-piston floating unit in front and just a single piston at the rear.

Mind you, with only 35kW to modulate, that may well be all that's required; we'll reserve judgement until we've tried it.

The all-digital instrument pod includes a speedometer, digital bar-graph rev-counter, odometer, two trip meters clock, fuel gauge and fuel-consumption display.

BOTTOM LINE

The Honda CBR500R retails for R69 990, which includes rider training through the Honda Academy, a two-year, unlimited distance warranty and 12 months' roadside assistance.
