Small-Displacement Class Considered for 2015 AMA Pro Racing Season

More and more manufacturers are entering the small-displacement sportbike market and AMA Pro Racing has taken notice, opening the possibility of adding a new racing class representing the growing segment. With plans to consolidate the Daytona Sportbike and Supersport classes and the Vance & Hines Harley-Davidson series signed through 2015, a spot will open up on race weekends for another racing class to support the premier Superbike Championship. The logical choice is to introduce a new small-displacement class.

475cc NS400R. Marquez and Spencer.

Winter may be here but I seem to be as busier than ever, maybe the economy is finally turning around. At my last UK track day of the year I had some fun testing this little beauty.  It’s a late eighties NS400 triple bored out to 475cc and it felt sweet as I zinged round the GP Arena track at Silverstone.   Being stripped bare to reduce weight gives it a very respectable power to weight ratio which means it could live with 600s (on the twisty bits at least).

Report: Honda to Increase NC700 Engine Displacement

British site Visordown reports Honda will release an updated version of its NC700 series with a larger engine for 2014. The larger versions will reportedly carry an extra 50cc, pushing its displacement to 720cc from the current 670cc used on the NC700X, NC700S and Integra scooter. But why would Honda introduce a larger engine so soon after introducing its NC line in the 2012 model year?
