TTR250- First ride review

**dino3310** · 12th January 2011, 20:43

i dont bother with dropping psi to suit conditions anymore, i just keep the pressures recommended on the Tyre itself.
different tyres will perform better than others at different pressures, you will have to find what works best for you and the tyre on at the time. everybodys got there own preferences.

i use to run 18 rear and 22 front offroad with mx tyres but now just cant be bothered mucking round with pressures, i dont ride hard enough to find traction limits if i do then i slow down

Off road biased - 20f/18r
Road biased - 24f/26r

What size bike are those psi recommendations for? I'm assuming it's a bit bigger than my TTR250. Next step is replacing the Scorpion MT90 with a Dunlop 606, I had to take it a bit easy going up the steep dry dirt tracks as the rear was starting to lose it when throttle was applied. I would have never made it out had it been wet, that papa clay is a challenge when wet.

Pretty much generic.
I don't go below 18psi to avoid spinning the tyre on the rim and pinch flats.

Do you have rimlocks?

The higher the pressure the more the ride quality depends on the suspension being up to it.

I've got rimlocks on the rear, and will add one to the front (with hd tubes). And I've been running 18 up front and 18 in the back, seems to work well on the road as well- but I will get a small hand pump and add 5-6psi on the rides back home.

I wouldn't bother with a front rim lock if you're going to stay >=18psi.

Some tyres are just picky with pressures. The MT21 rear I ran bounced off rocks until 18psi whereas the Mitas E07 rear was happy up to 26psi or so.

Now I've just got to get my act together and learn how to fix a flat while out in the field. I've seen some amazing youtube videos of guys changing them in about 2-3 minutes.....so it can't be that hard.....

it is that easy in with all the gear,stand and of course MX tyres. i can change my MX tyres in 15-20 mins on the garage floor but with the stiffer DOT rated ones espeically when there new im looking at least 45 mins.

have a practice at home get the tube out and put it back in, youl get faster and practice makes perfect.... i like watching the enduro boys like in the I.S.D.E amazing how fast they can change there tyre in crap conditions.

The secret is to practice on the front tyres only.
You'll feel like a tyre changing god

**zeRax** · 14th January 2011, 19:40

personally i think tyre sizes count for alot of it, i had a skinny tyre on the 125 at a point, and even thou it was a new tyre ( of course we have all ridden on plenty of brand new tyres ) it was like ice, ,

ever slid a 125 out sideways around a corner without trying ? ( edit, let alone on a straight, and at 24 odd psi )

i just put a new MT43 road legal trials tyre on yesterday and , it is a stiff beast in the sidewall (compared to previous knobbly like 606 and mt21'st etc ) , im sure i could run that bugger flat with out too much hassle

what i mean is tyre width, tread pattern etc, best to think about your contact patch and what pressure is doing to it imo, everything is horses for courses and you gotta suss out what feels best for your tyre and the way you ride, and also what feedback from the road u feel comfortable with

ive been getting down to around 12-16 psi off road without problems, but i have also thrown knobs off on road at 15 odd psi, but the only thing i have gone up past 22 on on the road was dr650 and purely thinking about longevity of tyres,

( edit , think not only about all this stuff above, but its about asking a bike with X torque to move X mass with X contact ) whast ur asking the tyre and connected to bike and surface moving your bike and your mass

fuck it this post is worthless anyhoo! ;D

I just picked up the hd tubes- damn! they are heavy! While I don't have a normal set of tubes to compare with, I'm thinking that these tubes might have some effect on street riding, am I right?

Yes. People will point and laugh.
