I bought TVS Suzuki Fiero around two years back. I never had any serious problems from this bike.
The bike is very reliable. There has been not many instances where I needed to kick twice for start. (my last bike a splendor had a problem of getting offed even at good speeds). The bike has a good pickup. It also reaches 60 kmph without your great attention. Its sound beating is decent and lovable. The light focus of the bike is too good (though it doesnot look as it is). I am not a guy to reach a three figure speed. My max was 90 kmph. So I cannot tell of the feel of the high speed. But at my max it is stable (I think the latest got much more stable due to Rectangulat Swing Arm). The mileage is 55 in city traffic.
I rate this a bit lower, but adjust for the power it gives. The spares are very reliable. My brake linings have come a longer for 11000 km (My previous bike had its last at 7000). This is an example of the quality built into the problem.
But as every good produst has some negative shades, I will list a few. The looks are not so attractive. The front guard is hit in the middle due to sudden braking. (so watch out for the middle of the front guard for its paint surprisingly vanish). I think the front shocks are abit too soft leading to this problem. I think the engineers should take this serious. The paint also fades a bit faster. Especially on top of your petrol tank.
Restis fine. As a person who used it for 2 yrs 11000 kms, go for the product. It is reliable and economical. The latest models are good looking too.
