Honda Australia’s announced its new naked bike pairing – the CB300R and CB1000R – will go on sale locally in June 2018, but no prices yet.
The CB1000R naked flagship is powered by a retuned version of the engine found in the “previous-generation CBR1000RR”, and is capable of 143hp at 10,500 and 104Nm at 8750rpm in its new guise.
Honda claims 16 per cent more peak power at just over 10,000rpm, and five per cent more torque in the mid-range.
Shorter gearing also adds to the increased flurry and tempo of the CB1000R, which Honda says makes it ride “harder” than the CBR1000RR in the first three gears. The engine has an assist/slipper clutch.
The engine tweaks from the door are aplenty: the pistons are now forged rather than cast, there’s higher valve lift, the throttle body is now 44mm (up by 8mm) and feeds larger inlet ports, and the airbox is new. The compression ratio has increased to 11.6:1, and there’s a new 4-2-1 exhaust.
The chassis is centred around a newly developed steel backbone frame, while the suspension is Showa – a Big Piston Fork and fully-adjustable monoshock at the rear.
Despite its stripped-back nature, the CB1000R’s considerably heavier than the sportsbike, largely attributed to its use of a 16.2-litre steel fuel tank and aluminium bodywork instead of lighter plastic options. Honda says that only six exterior parts are made from plastic.
Wet weight of the CB1000R is 212kg, which is still 12kg lighter than the previous generation CB1000R which was on sale in Australia way back in 2008 and 2009.
The new CB1000R has a swingarm-mounted mudguard, which is a first for Honda.
The electronics package includes a ride-by-wire throttle, four riding modes and switchable traction control.
The single-cylinder 286cc CB300R uses the same styling cues as the CB1000R for a minimalist result. The machine uses a steel-trellis frame, 41mm upside-down front forks, boasts a UMI-actuated two-channel ABS system and a single disc four-piston caliper Nissin brake package.
