Which Michelin inner tubes please!

[ninot7]

Got my Mission Trailmaxes on order to replace my stock STRs and wanna chuck in some new tubes. 
looking at the standard Michelin ones. 
are these the correct ones? 
21MD and 18 MG?

 

reason am asking is that the 18MG that i actually found on ebay dont have the 150/70 18 size written on them.

 

please advise!

thanks

You're fine, those will work as long as you're staying with the stock sizes.

yes the tyres are stock sizes. I was just wondering whether there are different types of the Michelin 18MG is that makes sense.
