Heavy Bike?

The term 'heavy bike' is the biggest, most offensive slang in the history of motorcycling.
Sport bike manufacturers and engineers work day and night just to figure out ways to shave few grams off of a motorcycle in order to improve the power to weight ratio and yet... We don't refrain ourselves from calling them 'heavy bikes'.
It's like calling a person with a slim and smart figure "FAT" or calling a Ferrari "HEAVY".
It's a very harsh thing to say.

Anyhow, there are quite a few so called 'heavy bike' repair shops and 'motorcycle boutiques' on Main Defense Road; just around Adil Hospital. I often see people bringing their so called 'heavy bikes' there. But since its an upscale posh area; expect to pay a lot of $$$.
Alternatively; you can try the motorcycle market around Lahore Hotel which is practically full of all kinds and types of "مستری بادشاہ".
Hope it helps.
