MOTOINNO TS3 TEST RIDE P98 sion cause it to compress under load, and thus to reduce rake and trail, making the handling more nervous, while conversely assisting with turn-in to the apex of a given bend. Furthermore, the fact that steering and sus- pension are coupled together means that one influences the other to the detriment of each, especially, once again, under braking. But the fact that a tele fork is still today the go-to option for motorcycle manufacturers in ev- ery single continent—irrespective of price or performance—results from technology having been de- veloped to paper over these de- ficiencies, even if some of these solutions bring added problems in their wake. So, an upside- down fork is not only heavier and more costly to manufacture, but also has the propensity to lose all its damping oil should a fork seal fail—although its increased torsional stiffness can improve handling by reducing or eliminat- ing deflection, while also de- creasing the unsprung weight, which enhances suspension compliance. The reluctance of manufacturers—with the notable exception of BMW—to risk public disapproval by adopting avant- garde technology for the highly visible front end of their models, has meant that, more than a century on from when Scott in- vented it, the tele fork still rules. That isn't for lack of trying to find an alternative, though— and not just from BMW, which today remains the only volume production manufacturer to fit what mechanical luddites term a funny front end to their customer models. Still, so far the German company's engineers have yet to display much original thought in concocting an alternative front suspension design, since the Telever front end adorn- ing their range of mainstream Boxer models is an outright duplication of the Saxtrak front suspension design created by British engineer Nigel Hill for the Motodd Laverda and Saxon Triumph road racers a decade before BMW dreamt up their copy, but which he unfortunately omitted to patent. Conversely, the Duolever fork BMW fits to its K-series models is a copy of the fourche Fior invented by maver- ick French designer Claude Fior Alan Cathcart got the chance recently to test the latest—and much improved— version of the Motoinno TS3.
