KR left off entry list

Having featured on the provisional entry list as TBAs in November, the team owned by three-time world champion Kenny Roberts were absent from amended version completely.

KR's participation has been in doubt for some time for financial reasons.

After losing their manufacturer tie-in with Proton in 2005, the team paid for Honda customer engines to fit to their own chassis the following year, but were forced to run an almost totally unbranded bike due to a lack of interest from sponsors.

But a switch to 800cc rules last season worked against them.

Without the might of a factory behind them, they were forced to develop a new chassis with only one rider - ex-world champion Kenny Roberts Jr -, a down on power Honda engine and Michelin tyres that were inferior to the Bridgestones used by half the field.

After their relationship with Honda turned sour last year, KR had hoped to either conclude a deal to use Ducati engines this season or to run MV Agusta's works outfit in World Superbikes.

The latter is now impossible, but it is believed that a package could be put together to allow the team to run in the second half of the season.
