CRF's Only Forums

Hi all,

I bought my daughter a 2004 CRF 70, nice bike and very clean. The rear tube valve stem tore around the base and I though it was just old rubber. A friend told me it might need a rim lock because the tire may have spun causing the stem base to tear. Can a 70 generate that much torque? Also, my local dealer said that 2003 & older CRF70's had 12" rear wheels and 2004+ had 14". He said that they don't stock the 12" tubes since they don't sell many. I am pretty sure that the bike is a 2004. Is he wrong or am I (do the newer 70's have 14" rear wheels?

Thanks

Calvin

Hey Calvin welcome to the site.

For starters, you are correct. The CRF 70 has a 12" rear wheel. However the front is a 14".

Front Tire 2.50-14

Rear Tire 3.00-12

The CRF's started in 2004, prior to that they were XR's.

I believe the 2003 XR 70 still had the same size wheels.

And no, they do not produce enough torque to spin a tire on the rim unless it was really underinflated.

Thanks ~....

I did some more research and found that they did go to much larger wheels starting in 2005; 16 Rear, 19 Front. The seat height remained the same meaning they sacrificed a couple inches of shock travel. I guess the ride would be smoother, but not as stable???

This is a good forum for a newbie. Glad I found it.

I have a 2007 CRF70 and it has a 12" rear and 14" front Where did you find info on 16 and 19"? I'd like to see a 70 with 16 and 19's.
Oh yeah by the way welcome to the site!!!

Now that I read some of the odd spelling, it might be a foreign version??? I certainlty might be wrong, but the local dealer parts guy says that they do not stock 12" tubes anymore because Honda upsized the CRF 70's wheels.

Here is a site with fische on the 06 70. It even states a 12" rear you'll have to search it but is on there.

Thanks for the info. So why would my local daeler parts guy be so clueless?

Because they are! They have no idea what they sell. My honest opinion.

+1.

Last time I was in there, they tried to give me brake pads for a disc brake for a 2003 xr100! They insisted that the brakes were disc, until I walked about 15 feet over to the showroom area and asked them to show me the rotors, calipers etc...

From the honda website, 14 and 12.

Thanks for all the replies. I guess I will tell the Dealer to Get with the Program!
