How Much Air Pressure?

Featured Replies

New to trials. Have a Honda TRL200 Reflex that I restored two years ago. Hoping this year to actually get in some practice riding. I'm middle aged... about 155 lbs.

My question is about air pressure in the tires. I have a honda CR80... smallish dirt bike that I've been riding for a few years. Not competing just pleasure riding in the woods, etc. The way I set the pressure is simply by feel. Soft enough so I can press in about half way on each tire with my fingers.

This less that scientific method has served me well for the rocky, pebbly, muddy & wet areas I normally encounter.

What do you folks recommend as a starting pressure for trials?

That thing is CLEAN!!!

I would say 5-7 psi in the front and 4-5 in the rear.

I can't tell if you have a rim lock in the rear, but if not, you should install one if you'll be riding low tire pressure.

I have run my rear tire as low as 3.5 for slippery conditions, usually 4 lbs

And my front bashes the rim at 5 lbs so I run 6lbs but I'm 200lbs

Pressure changes with temperature so you check it often

Hey what is that Reflex like to ride? That's a nice little bike there

What do you use to measure that low a pressure. Digital guage or ??

Clean? Well, it should be since it has yet to see dirt : )

As to riding it, again, I cannot give you much more until I actually do ride it more than around my back yard. To be sure, it is a very strong bike compared to my CR80 and I'm a bit nervous about riding it. The engine has been rebuilt and the compression is very high.

Found this video on YouTube. This is the exact same bike in every detail.

I have it registered as street legal although it is really much too slow for the street. This is a requirement though for some park areas here where I live. All the lights are there but I can remove the battery and it runs fine. The signals will not flash at idle and the headlight dims a bit with the battery removed.

Bikes like yours can often be run with a dead battery, but you can sometimes do serious damage to your electrics by running it with the battery removed.

Better safe than sorry.

Look for an ATV tire pressure gauge or fork air pressure gauge that caps out at 10lbs or so

Regular tire gauges are not accurate at low pressures

Apico do a tyre pressure gauge up to 15psi and they retail about £15. they also have the valve to release the pressure to what you require

Thanks for the heads up on the battery. I will put one in : ).

Also thanks for the tip on the ATV-type pressure guage. Will search for one online.
