And since every bike they're thought about and which made it into production was slightly bigger than initially specified, rumors about the 375 Duke for 2013 have already started to pour in. KTM has already announced they had a 350 Duke in plan, following the general trend of the industry with the small-displacement models.KTM also declared that this new Duke could reach 375cc, though. And with all the previous examples, it might be the case this time too: KTM usually goes for the biggest numbers they announce, so the 375cc engine might just become reality.Even more, it's possible to see a V-Twin engine, which will also be a novelty for the Indian market, as it is saturated with single-cylinder bikes. With the ever-increasing fuel prices, it looks like customers started to favor smaller bikes in both US and Europe, since bikes like the Honda CBR250 and Kawasaki Ninja 300 have already so many fans.
