About the AMA Pro Grand National Expert Singles Championship
Competing on short tracks and TT’s, the stars of AMA Pro Grand National Expert Singles have to switch gears on their single-cylinder production-based 450cc bikes. Putting the emphasis on more strategic and intricate racing methods, the shorter courses contain less lengthy straight-a-ways and demand a high level of creativity in order to get to the front of the pack and maintain a competitive position.
Eligible bikes in AMA Pro Grand National Expert Singles include recent model year versions of the Honda CRF450R, Kawasaki KX 450F, KTM 450 SX-F, KTM 450 SX-F FE, KTM 450 SX, Suzuki RM-Z 450 and Yamaha YZ450F.
As with all classes of AMA Pro Flat Track, the Expert Singles run on purpose-built Goodyear tires and are fueled by Sunoco Supreme 112 race fuel.
The stars of AMA Pro Flat Track will whip out their single engines on the very first week of the season at the DAYTONA Flat Track. Brad Baker collected the 2013 Expert Singles #1 plate while on his way to capturing the 2013 Grand National Championship.
