hi drift, congrats on your new bike ! btw what part of the bike do you wanna modify? it all depends on your budget and also your riding style.
according to me, the first mod you could do is to fit a good suspension fork first, followed by good disc brakes, followed by good wheelset so on and so forth. a decent suspension fork could cost you anywhere between 10,000 to 35000
good quality hydraulic disc brakes would cost anywhere between 6000 to 15000 per wheel
do let me know the kind of riding you intend to do on your viper, so that i can guide you as to what to go for.i'll be glad to help. unfortunately getting good aftermarket bike parts is not easy in india. you'll have to buy stuff online. thats what i do. for starters, you could go visit Bicycles | Bikes | Mountain Bikes | Road Bikes | MTB Bikes | Bike Parts | Bike Frames | Road Frames | MTB Frames for a complete lowdown on the prices and shipping rates.

ride hard. wear a helmet!
