In the last post ‘what should you know about before importing bike/car’ you were fed up with rules and regulations for importing bikes. Now let’s know some technical (fancy terms) which will be helpful to you while importing bikes.
Supersport: term used to denote bikes which have 4 cylinder engines and engine should be less than 650cc.
Maxi sport: term used to denote bikes which should be below 750cc in case of 4 cylinder engine and should be below 1000cc in case of twin cylinder V type engine
Superbike: term used to denote bikes which are powered by engines of sized around 800 cc to 1100 cc.
Hypersport bikes: term used to denote bikes powered by engines are usually sized around 1100 cc to 1400 cc
Though they are categorized there is no definite methods for classification some of the bikes falls under more than one category. Suzuki, Honda,

MotoGP bike and it’s sibling
Now we will see the technology behind the hottest sports bike ‘Honda CBR’ which is derived from its big brother 2006 world champion Nicky hayden’s Honda RC211V
Boeing 747 takes off at 320 kph—it’s the top speed of a Ferrari. MotoGP bikes break two bills with power to spare. MotoGP is the ultimate motorcycle racing series, a pure combination of advanced technology and athletes psychotic enough to pilot these overpowered machines at speeds most wouldn’t dare with four tires on the ground. Riders lean so severely into turns that they scrape their elbows and knees on the asphalt; brake so hard they have to force their weight over the back end of the bike to keep it from flipping; and accelerate so violently that their front wheels often leave the ground. The only reason the riders make it out alive is because they drive the most precisely engineered motorcycles ever made.
Take, for example, Honda’s RC211V—the bike 2006 world champion Nicky Hayden rode to victory in the Red Bull U.S. Grand Prix last July. The most advanced machine on the MotoGP circuit, it weighs less than 150kg yet packs more than 240 horsepower (around 20 times more than recently launched pulsar 200cc). It rockets to 160 kph in less than five seconds and can hit 346 kph. Oh, and it costs about $3 million (13.5 crores).
The Technology…
- Chassis
When you’re leaning the bike so far over that you’re almost parallel to the ground, suspension doesn’t do much; the frame itself has to soak up some of the bumps to keep the rider from losing control. Honda alternated the frame-wall thickness on the RC211V and CBR so that key areas can flex. - Engine
The MotoGP league mandates that every bike have a 990cc engine (2007 regulations mandates 800cc), but that’s about it. Honda chose five cylinders versus three or four because five smaller pistons can get up to their 15,000rpm redline faster. The CBR sports a four-cylinder with a marginally sane 11,650rpm redline. - Suspension
Instead of attaching the rear shock to the frame, as is conventional, Honda hid the suspension on both bikes inside the arm that connects the wheel to the frame. This freed up space for engineers to move the engine and fuel tank to tweak weight distribution. - Fuel Injection
MotoGP bikes need to accelerate fast and still have power at high rpms. To achieve this balance, Honda inserted a second bank of fuel injectors that kick in north of 5,500 rpm, doubling the amount of fuel in the cylinders. The CBR has a dual-stage system as well, but it’s tuned for lower top speeds (“only” 176 mph). - Tires
The middle section of a MotoGP slick is smooth, hard rubber that can handle speeds up to 346kph. The edges are more porous and soft for grip on sharp corners. The stock bike gets treaded Bridgestones or Pirellis rated to withstand a measly 240kph. - Radial-mounted Brakes
To fit the massive 320-millimeter front-wheel rotors necessary to stop the RC211V, Honda had to offset the calipers from the forks. The CBR has the same size discs, but they’re made of steel, whereas the RC211V’s are made from lightweight carbon fiber.
