| It came with a 90/90-21 front [[tire]] and a 5.10-17 rear tire. Stopping was achieved via Single 260mm disc in the front and a Drum in the rear. The front suspension was a Gas telescopic forks while the rear was equipped with a Alloy swing arm single shock. The ER500 Dakota was fitted with a 22 Litres / 5.8 US gal fuel tank.

| Gilera ER Dakota 500
| |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| The first the world saw of the new Gilera four-stroke during the 1980s was at
| |
| the biennial Milan Show in November 1985. Not only did the famous old Arcore
| |
| factory have one of the biggest and most impressive stands at the exhibition,
| |
| but also an exciting new thumper in the shape of the 350 Dakota trailster, with
| |
| the added promise of a larger version in the pipeline.
| |
| And Gilera's first new four-stroke in over a decade showed that it wasn't
| |
| just two-stroke models which were receiving the
| |
| modern treatment in the Arcore R&D shop.
| |
| | |
| FOUR-VALVES
| |
| | |
| Designed by Ing. Lucio Masut, the newcomer employed every trick in the book -
| |
| including liquid cooling, four-valve cylinder head, twin exhaust ports, twin 25
| |
| Dell'Orto carbs, double overhead camshafts driven by toothed belt, a balancer
| |
| shaft (gear driven directly off the crankshaft) multi-plate hydraulically
| |
| operated
| |
| | |
| | |
| wet clutch, five-speed gearbox and Japanese electronic ignition and electric
| |
| starter. There was also a forged piston and a one-piece crankshaft which ran on
| |
| anti-vibration ring bearings. The pity was that all this hi-tech only produced
| |
| 33bhp at 7,500rpm from the 348.8cc (80 x 69mm) mill. But at least the 500 (which
| |
| took another eighteen months) promised a 25 per cent power increase with no
| |
| additional weight to speak of.
| |
| | |
| DUAL-PURPOSE
| |
| | |
| Gilera had opted to build a dual-purpose, on-off-roader rather than a pure
| |
| street bike because, at the time, sales of machines like Yamaha's Tenere were
| |
| riding high. The Paris-Dakar style was all the rage both in Italy and around
| |
| Europe; in fact everywhere except Great Britain! Even though the Dakota's power
| |
| output was disappointing in view of its technical gizmos, the in-house Gilera
| |
| styling job was generally accepted as being superb. As proof of this, author
| |
| Alan Cathcart picked the Dakota to feature as only one of two machines with
| |
| engines of less than 750-class in his 1988 book, Dream Bikes.
| |
| | |
| | |
| But besides the lack of power, the wide 5imp. gal (231tr) fuel tank and
| |
| sculpted bodywork was slammed by serious off-road riders for its enforced
| |
| 'knees-out' riding stance which, unless the rider adopted a more rearward
| |
| seating position, (which then altered the weight distribution) was extremely
| |
| uncomfortable.
| |
| | |
| THE ER VARIANT
| |
| | |
| Gilera responded in a positive fashion by introducing the ER variant in 1987,
| |
| just as the 500 model 492cc (92 x 74mm) came into production. The ER was
| |
| targeted firmly at the committed green lane rider, with its smaller 3.3imp. gal
| |
| (151tr) tank and the twin coolant radiators now shrouded by abbreviated plastic
| |
| panels. These two changes enabled the driver to sit further forward in a more
| |
| comfortable position. The original model was also retained and, with both
| |
| versions available in 350 and 500 form, this meant that there were actually four
| |
| different Dakota models to choose from.
| |
| With a dry weight of no less than 3241b (147kg) in both engine capacities,
| |
| the Dakota was one of the heaviest machines in its class. This showed up most
| |
| under heavy braking when the single 260mm disc and its Grimeca four-piston
| |
| caliper was stretched to its limit to cope. The Gilera engine was the most
| |
| sophisticated in the on-off-road sector of the market, but with its great weight
| |
| and power-sapping ultra efficient (quiet!) exhaust system it was not really
| |
| suitable for pure competition, even in its 500 form.
| |
| However, the engine was very strong and the square-tube enduro-type chassis
| |
| was fully capable of taking more power. The result was that at the Milan Show in
| |
| 1987 Gilera launched the XRT.
