Hi

I have fitted rimlocks onto my klr

What sort of tire pressures do you think I can drop down too on knarly bits like the south side of Porika etc?

On my wr I run 11psi without problems but I'm assuming the klr's obesity issue will make 15-20 a realistic minimum?

I normally run 30 on the road and light gravel but that makes things a bit skittery in the rough/sliipery stuff.

I've got a tkc front and e09 rear

cheers

I used to run 15f/12rpsi on my Xr400 with no problems trail riding.
I would thought that 15-20 would be no problem on the KLR. If the going got real nasty off-road, I'd warrant that 10-12 wouldn't be a problem.

The one problem you could have is re-inflating.
Unless those TKC's are run a correct pressures on the road, they'll melt.

15-20psi sounds about right.

Porika, Maungatapu etc are very rocky so your limiting low-pressure factor will be pinch flat protection. For that I would suggest 18-20psi front as a minimum, and watch the sharp hits. Rear 20-25psi, something like that.

The south side of the Porika is in pretty good (err, better) condition, IIRC. Went up it in the middle of the year and it was a lot smoother than during the DB in January. Norf side has more potholes though, so bumpier and some interesting erosion channels.

Nelson side of Maungatapu is up the sh!t, quite chewed out.

Depends on the rims - my XT has a raised knurled ridge in the bead area,this locks into the tyre bead and it doesn't need rim locks - but you do need a bead breaker to change a tyre.The TLR200 has 2 rim locks and the rear tyre still slips,but 3psi is not a lot of pressure.

Thanks Guys

I'll give 20psi a shot on the Maungatapu/Porika tomorrow and see if I can avoid ending up on my bum

cheers

18f/20r should be sweet for those tracks.
Even 20f/22r for a bit more roadability inbetween.
