Post GST, the goods tax, which currently is at 30 per cent, will go down to 28 per cent for motorcycles below 350cc engine capacity. Motorcycles with engine capacity over 350cc will be considered as a luxury investment and will attract a total of 31 per cent tax; 3 per cent more over affordable motorcycles. This turns out to be a good deal for people who are potential buyers in the sub-350cc category. There is a lot of confusion around the pricing of motorcycles post GST (Goods and Services Tax) is implemented.
