Shipping bike Canada to SE Asia or India / estimating crate dimensions for quote

[ride.climb.dream]

Hi All.

Hoping for some help as I am planning for my first big global moto journey!!
I am in the planning stages, but have a loose route/timeline in my head, now need to start checking if the logistics are possible and if the costs match my estimates!

I'm American, but understand it may be easier/cheaper to ship out of Canada, and I can get the bike there if needed.
Desired route is to ship by air in November 2019 from US/Canada to SE Asia (Singapore or Kuala Lumpur seems like the best bet?) or India (if the Thailand situation is not possible?) and begin riding west from there on a two years journey.

I am familiar with the Air Canada "ship your bike program", but it doesn't include Asia and ends in Sept, and I am hoping to leave in November. I did get rough quotes with them for a basic dangerous goods shipment based on my desired date/cities. Could anyone recommend shipping companies to check with for quotes given the countries I am working with? It looked to me that James Cargo is only from shipments out of the UK, and that Motorcycle Express only covered Canada to Europe and variations.

Also, estimating dimensions/weight to get an accurate quote! I have read all about the crating process and how to reduce the total dimensions. However, I am wondering what people do when they are getting quotes during the planning stage?
The bike I plan to ship is a DR650. Do people do a trial in the garage like removing the F wheel and bars and see how small you can make it and then use this figure when getting quotes from shipping companies? Also how do you properly estimate the weight including racks and gear, as I am assuming this can go in the crate with the bike?

I appreciate any help or advice!!

Thanks!
