I gone through the product which was quite good but I found the new "Royal Enfield Thunder Bird twin spark" *at par to R15. At the almost same price & with a better mileage the 350 cc bike gave me more pleasure on the roads. Its comfort level is much better than R15. Although the looks can be a decisive factor for some but for others Thunder Bird twin will be a much reliable option. This is the feel of true Indian Metal.
R15 has better looks in sports bike segment & its speed gain is excellent but for six speed transmission the engine capacity is limited coz when you slow down at sixth u need 2 gear changes & the gain capacity at 5 & 6 makes not much difference seems close to.
On controlling I would grade the bike to be equally perfect. The rare disk is lovely on breaking & de-acceleration is very sound.
If I find something more useful I will add to it later on ;
Till then -Happy Riding Guys!!!!!!!!!!
