Honda CBF Stunner FI review, test ride

30th Sep 2009 7:00 am

Stunner FI comes with class-leading style, great quality, a willing and frugal engine, superb riding position and nifty handling

  • Make : Honda
  • Model : CBF Stunner

Just a few visual changes differentiate the the fuel injected CBF stunner from its carburetted version. Its styling is still in a league right up there with the best. Black finish is liberally used while neat alloy rims maintain a contemporary air. The bike gets a powerful headlight with a well spread beam, and is set flush within the familiar, dart-shaped front fairing that stretches back into the fuel tank region.

Handlebar-mounted controls such as the nice switches, clutch and brake levers and soft grips remain unchanged. The only addition to the fuel-injected Stunner variant being the bar end weights. The instrument bay gets a new malfunction indicator icon but the rest of the fascia is the same with a bold-looking speedometer and fuel gauge set prominently. Although the Stunner FI misses a tachometer this bike does deploy a trip counter in addition to an odometer.
This Stunner retains the familiar, muscular and voluminous fuel tank, which looks a treat and provides the right support to a rider’s inner thigh region.

The new bike gets marginally altered graphics with a golden treatment now visible on its engine casing. While the stylish side panels get three-dimensional PGM-FI decals, a smartly split riding saddle adds a sporty touch as do coloured suspension springs and a newly exposed drive chain. Alloy footrest mounts are standard kit as is a tyre hugger at the rear. The tail fairing section is tall with the brake warning light itself a simple, yet tasteful bit. There’s good quality all round, immaculate paint lustre and perfect fit-and-finish, just as can be expected from any motorcycle branded with the famous winged logo.

The CBF Stunner FI doesn't use a kickstarter, and deploys a maintenance-free (MF) battery to power thumb-operated engine starts. Tthe air-cooled, four-stroke engine with a single cylinder displacing 124.7cc now uses fuel injection technology along with Honda’s proven PGM-FI system. An ECU controls the operation after reading data sent in by a bank of eight sensors including oil and oxygen details  to get the perfect blend of air-fuel mixture in any given condition, at every engine speed. Peak power is up a morsel relative to the older model, with 11.6bhp built up at 8000rpm.

The Stunner FI also provides a bank angle sensor calibrated to safely cut fuel supply and prevent a fire in the event the bike tips beyond a predetermined angle.

The Stunner FI outputs 1.14kgm of torque at 6250rpm.The Stunner FI’s five-speed gearbox shifts with good feel in a one-down and four-up pattern. Its clutch is light, feeling spot-on for repetitive city operation; all the gear ratios remain unchanged from the carburetted bike and just as properly suited to slow-moving Indian city traffic as always. Maximum speeds in each gear are up now, thanks to the engine now revving slightly higher than before.

The Stunner FI goes one up on the original Stunner with fuel injection supporting easy cold starts and a clean power delivery. The power band is nice and wide and the fuel-injected engine feels a bit buzzy at really high rpm, with some vibes finding their way from the seat and footrests through to the rider. The CBF Stunner FI is quicker than its predecessor from zero to 60kph, taking 6.36 seconds for this sprint, on its way to a top speed of 106kph flat-out in top gear.

The Stunner seat is well padded, with a riding stance that moulds the rider into a slightly weight-forward, still-comfortable posture. Its low handlebar is complemented by slightly rear-set footpegs, which make for a sporty feel that doesn’t intrude unduly on comfort. Ride quality is a nice blend of plush and stiff, with the bike handling in a light, nimble fashion and always displaying solid stability.

The brakes — a 240mm disc in front and 130mm drum rear — are reassuring as well. Our best stop from 60kph to rest took 19.07 metres which, we are sure, could have improved if this bike had better tyres.
