Motorcycle Rentals (Mumbai)

Well I'm going thru withdrawls and even thou I see the traffic outside, I want to get out on two wheels. I usually ride nearly every day at home and I miss it. Does anyone know where I can rent a bike? I'd prefer a Bullet 350cc or 500cc but anything may do. I suppose it may be easier to buy one for the time I'm here but I don't know anything about the process in India.

Any advice? Places I could go? Thanks
