Moto2 bikes built by LaGlisse and BQR have taken part in practice and qualifying for the CEV 1000cc Extreme (Superbike) event at Albacete.
Moto2 machines, which feature 600cc four-stroke engines and a prototype chassis, were originally expected to replace 250GP from 2011, but a 2010 debut was 'announced' during last weekend's Qatar Grand Prix. Next season thus looks set to be a transition year, with both types of machine on the grid.
By putting the Moto2 machines on track in officially timed sessions, against known rivals, Dorna - which promotes both MotoGP and CEV (Spanish Championship) - is trying to gauge how fast the Moto2 bikes will be relative to 250GP competition.
In Albacete qualifying, the Moto2s beat everyone except the Extreme front row of Ivan Silva (Kawasaki), Carmelo Morales (Yamaha), Kenny Noyes (Kawasaki) and Javier del Amor (Yamaha).
LaGlisse Yamaha rider Angel Rodriquez claimed fifth place, 1.344sec from Silva, with BQR (Blusens) Honda's Daniel Rivas just 0.091sec slower.
To put those times into perspective, at the three tracks where both CEV Extreme and 250GP race - Catalunya, Jerez and Valencia - the Extreme bikes are generally around one second a lap faster than 250GP.
The two Moto2s were using Dunlop tyres - as are most CEV frontrunners, with the exception of Silva and Noyes, who are on Michelins. The present 250cc World Championship grid all use Dunlop tyres, although it is not a single-tyre class.
It was recently announced that Moto2 will be a single-engine class, with powerplants supplied by a to-be-announced manufacturer.
At least one or other of the Moto2 bikes on track at Albacete will thus have to accommodate a new engine before next season - both if the rumours of a Kawasaki supply are confirmed - although the inline four-cylinder format (as used by the Supersport road-based engines in the BQR and LaGlisse Moto2s) is expected to remain.
The Moto2 machines will not race at Albacete.
