Milestone in mileage

Far back in 1985, Hero Honda cd 100 was the first four-stroke bike to take a tentative step in the Indian market. Since then it's going great guns. The product has been rated the second best model behind its new avatar -- the Splendor -- among the two-wheeler models. cd 100 has introduced only some minor changes in its appearance and engine design since its launch and these are basically to comply with the existing norms rather than spearheading initiative. Nonetheless, the bike rides high on popularity. It scores 34.80 per cent in vehicle and engine design to rank third among others in the segment. The high score in this parameter is primarily because cd 100 is the most fuel efficient bike with an average of 81.7 km per litre. This advantage of fuel economy is because it has the least weight among all the four-stroke motorcycles. However, its compression ratio is just 8.8, which is much lower than the best tvs Suzuki Fierro at 9.4. Its other features like manual transmission, carburettor fuel supply system and dry air filter indicate nothing above the normal practice. In case of emission control system, cd 100 top ranks with a score of 29 per cent. This bike, along with Splendor, are the few models to have some sort of control equipment An air injection system along with closed loop positive crankcase ventilation (pcv) system has been provided in this product but other than that it is not fitted with any other control gadget. Where the question of actual emissions arises, the vehicle is 72 per cent better than the regulatory norms and ranks 1st among all the bikes. The co emission is .62 gm/km, while hc and nox together form .95 gm/km. The product also has the lowest co2 emissions with 26 gm/km and commands greater respect in this aspect than its other counterparts.
