Hi, The subject of this topic being the 2009 P-220, I think we need to refocus here. If you read shootouts of some of the best performing bikes in the world, you will see the Yamaha's R1 (998 cc) pitted against Triumph's Daytona 675 (675 cc), with a difference of about 325 cc. The R15 may be a 150-cc bike, but it is also a top performer, which is why it is compared with the latest top performer, the new P-220, with a difference of about 70 cc.
It is not the capacity but the power and performance figures here that matter. When the 2001 Pulsar 180 was launched, it blitzed the likes of stock Shoguns and RX-135's. Though there are engine differences (2-stroke v/s 4-stroke) and capacity differences of 45 to 80cc, there are approximately the same power output figures of around 14-15 bhp. Regards, Pravin
