Tales from telefork evolution

When Rudolph Schleicher and W others at BMW decided to give the telescopic fork a try as a stiffer, more accurate replacement for the spidery (and, frankly, Edwardian) girder fork, they quickly evaluated most of the forms we are familiar with today. Understandably motivated to save weight, they began with 28mm tubes.

When the Second World War ended, BMW front suspension was far ahead of other makers, as they were already providing most of the damping on the rebound stroke, and much less on compression. The reason for this is that the motorcycle's stability is much more affected by compression, or bump' movement, which tends to toss the wheel upward - possibly even off the pavement.

Front suspension was in turmoil elsewhere. Norton's first try at a tele provided no damping at all, other than that from its lubricating grease. Triumph didn't get around to providing unequal compression and rebound damping until the early 1960s, and several other makers quietly acquired BMW wartime R75 sidecar rigs just to have a look at the 1945 state-of-theart in fork damping.

Ducati Riding Experience

When I rode the Ducati DesertX to France last year, I did have a bit of an explore on some easy fire roads and gentle green lanes in the wilds of the Médoc area, but was left with the feeling that, had I the experience, the DesertX would have been capable of taking me along some more extreme trails to some even more exciting places. If only there was a way of finding out just how well the Italian adventure bike could cope with some more extreme terrain...

First Time Lucky?

It's ironic that the first all-new MV Agusta model to hit the marketplace right after Italy's No.1 trophy brand was acquired by Austrian giant Pierer Mobility, owner of off-road titans KTM, should be the company's first dual-purpose model of the modern era, powered by MV's all-new 931cc three-cylinder engine that's destined to form the basis of a whole series of new models in coming months and years.
