A second Honda CBR1000RR Superbike arrived at Daytona International Speedway Monday evening, and both of the new Honda Superbikes on hand made their presence known immediately with quicker lap times Tuesday morning at the Dunlop tire test.

Within a few laps, Erion Honda’s Jake Zemke had already done a 1:49.578 on the brand-new bike, faster than the 1:50.047 he turned on the CBR he shared with American Honda’s Ben Bostrom on Monday.

After recording Monday’s fastest time, Bostrom jumped right back in the swing of things Tuesday morning by bettering his time to 1:48.886 within the first 30 minutes.

Bostrom’s teammate Miguel Duhamel will ride one of the CBR1000RRs later in the day, but he is presently continuing development work on the CBR600RR Formula Xtreme racebike.

On Monday, Duhamel’s FX bike lost an oil fitting, which caused a dramatic and smoky oil leak and forced his team to replace the engine as a precaution. In his limited time on the bike, Duhamel and Crew Chief Al Ludington learned that 16.5-inch Superbike slicks upset the Supersport geometry of the bike.

Today Duhamel’s bike has different geometry, a different front end and a different specification engine. So far, Duhamel said, he is impressed with the braking ability of the light bike with Superbike brakes, forks and tires more than its acceleration.

The weather is excellent at the Speedway with temperatures in the upper-60s F by 10:30 local time.
