Honda’s new CB1100 EX

Honda CB1100 EX 2014For 2014 two Honda CB1100 models will be available: the standard Honda CB1100 and the new Honda CB1100 EX. Based on feedback from existing owners, the new EX provides the CB1100 with a new twist, while very much retaining what made the original bike so special.

The bike’s redesigned, larger capacity fuel tank, seat, sidepanels, passenger grab handle and raised headlight position all came out of time spent with bikes from Honda’s more recent four-cylinder history, while wire-spoke wheels are an effective and stylish reference even further back in time. The 4-2-1 exhaust of the Honda CB1100 has been replaced by a double-skinned 4-2-2 system.

A steel double cradle frame houses the Honda CB1100 EX’s 1,140cc inline four-cylinder engine, with 41mm conventional telescopic forks and twin rear shocks providing compliant and finely tuned suspension. The riding position is unchanged: upright and relaxed.

Centrepiece of the Honda CB1100 EX is its DOHC engine, finished in eye-catching sliver. It revs to 8,500rpm and features a compression ratio of 9.5:1. Maximum power output is unchanged at 66 kW at 7,500rpm, with peak torque figure of 91 Nm at 5,000rpm. Bore and stroke is set at 73.5mm x 67.2mm. Drive for the twin camshafts is via central chain, and the valve included angle is 26.5° inlet and exhaust. Inlet valve diameter is 27mm, with a 2.5mm stem; exhaust 24mm with 2.5mm stem. A single secondary balancer shaft ensures smooth running.

The twin silencers are 40mm shorter than the single exhaust fitted to the CB1100 and have been tuned to emit a soulful inline four-cylinder sound. The chromed downpipes also feature a double skin to prevent any chance of surface discolouration from heat build-up. Maintaining the benefits of a five-speed gearbox ­­– carefully matched ratios giving good response and acceleration – the new sixth gear is an overdrive, reducing fuel consumption while delivering lower engine rpm at highway speeds. Final drive is by 530 chain.
