To answer your question on Engine Oil. Motul is considered to be the best.
However, it also depends on the owner of the bike as to what he's got in his mind. Motul, Catrol, AGIP, Shell to name few.

Spares for ZMA-R/ZMR - We are in India, so get used to such things as "that part is not available sir". Either move on to another bike or find some alternate compatible parts. I have seen some struggle to get spares for my RX, so searching for spares is something I'm have prior experience.

I don't think any good bikes in India had low running for demand. If performance speaks for the bike, there will be people going for the bike. Take RX in India. Still crazy among the avid buyers in the 2t market inspite of major players have stopped manufacturing.

JV split - that's really sad thing to happen for ZMA and it's owners. Need to watch Hero's plan in the similar segment.

Yup,RX is the best when it comes to city ridding..You don't need a horn
while riding the RX..
If there is any bike which come closer to RX in terms of fun,zig zagging
through traffics,it has to be Apache Series..

I recently rode my friends P220..And the rear tyre was fishtailing when i was doing
105km/hr..I was pretty scared..Do A180 or ZMA rear fishtails or wobbles at high speeds?
Please give detail info on this.
