Perfect, thanks for all the info, Ill buy it.

:scooter:

If you are going travelling I would buy a couple, a spare is always handy.

I am riding from the UK to South Africa.

I was going to fit the Heavy Duty inners before I left, take my existing normal tubes as spares and then 2x punchture repair kits.

?

I wouldn't bring 2nd hand tubes, get 4 new x HD tubes and Puncture kits.
If you are getting punctured then you might as well fit another HD tube instead of a lightweight one which may get a puncture more easily.
Keep the old tubes for when you get back to civilisation.

Yep, no worries. My DR650 has 120/90-17 size tyres as well and these tubes fitted fine. Had no trouble with them so far, so yeah, I'd recommend them.

HD innertubes.
 

Thanks guys.

Ive bought 2 pairs of HD tubes.

Fitted the front wheel tube last night....was a swine.....punctured the standard tube I was removing, fitted the HD ok after some swearing and wishing I had smaller hands and wishing HD tubes were thinner.

NOT looking forward to changing my tyres from road to offroad once I hit the dirt tracks......fingers crossed I dont nip a hole in the HD trying to get the tyre off.

Anyway, only 2nd time Ive removed a wheel and tyre.......still learning :innocent:

Tube fitting.
 

Check out the motion pro T6 tyre levers!
The one model has a small lip on the end that stops it slipping in use and is a revelation to use.
The best I have used BY FAR!
They have a built in ring spanner at the other end.
Just choose the size for your wheel nut.
Soapy water helps too.
