Aprilia To World Superbike For '07 Aprilia is set to return to the World Superbike Championship in 2007, according to well-informed sources in Italy, with an all-new motorcycle that is set to debut in street guise at the 2006 Milan Show held in November. But contrary to Piaggio CEO Rocco Sabelli's conjecture earlier in the year, when he confirmed that Aprilia would return to the World Superbike arena at the expense of its continued involvement in the high-cost/low-return world of MotoGP, the bike in question won't be a sanitized street version of the company's pneumatic-valved three-cylinder RS3 former MotoGP contender. Instead, Piaggio engineering boss Lucio Masut, who has been tasked with creating the engine to power Aprilia's new Superbike contender at his Pontadera base inside the giant scooter factory, is understood to have concluded that only an all-new four-cylinder motorcycle has a chance to be competitive in World Superbike under the new 1000cc rules, as Sabelli had stated might be the case when confirming that Aprilia would return to the production-based form of World Championship racing. With fellow-Italian marque MV Agusta already building an inline four, Aprilia is understood to have decided that for marketing reasons at least, it shouldn't opt for a comparable format - hence Masut is understood to be working on a 1000cc V-four, which is likely to have an included cylinder angle of somewhere between 60 degrees and 75 degrees in order to permit compact installation in the aluminum twin-spar chassis being designed by the team led by Aprilia's frame guru,Gaetano Cocco. This would necessitate fitting at least one balance shaft, to reduce undue vibration, and not only would it remain faithful to Aprilia's narrow-angle vee philosophy, as expressed via the company's existing 60-degree RSV1000 and off-road, 77-degree SXV450/550 V-twins, but it would also have the effect of distinguishing the bike from the 90-degree Ducati Desmosedici V-four coming on line in street guise one year from now, (which may or may not eventually find its way to Superbike racing), as well as Honda's V-four products of the last millennium. However, it's not been revealed what cylinder angle this engine will adopt - whether a 60-degree vee like the firm's current RSV1000 V-twin, or a wider 72-degree layout (which has certain secondary balancing benefits), 75 degrees (as KTM's computer model told them was the minimum angle feasible to prevent masking the intake valves - hence the LC8 V-twin engine layout and the Austrian firm's MotoGP motor) or 90 degrees (as in Ducati's and Honda's V-four lay-outs). Time will tell which one Masut opts for - but don't expect such an engine to make an appearance in public until the 2006 Milan Show, then to debut in World Superbike the following year.

If the rumours (wishful thinking?) that pops up in the bike press regularly is to be believed we may be on the verge of Moto GP replica road bikes when the current 990cc capacity is reduced to 800cc in 2007. If this delicious prospect were true then perhaps the Cube would be homologated for road use, but kept at 990cc for WSB and likewise for the Yam M1 or Hondas RCV would transfer to WSB. Considering the fierce power the Cube has produced and the time available before 2007 to get the tranmission of this power through the chassis maybe Aprilia stand a real chance of lifting a 4-stroke crown to compliment their dominance of the 2-stroke class? p.s. twin, four or triple I'd probably still want an Aprilia[:)] Mother Nature rides a biker
