CRF 150F Front tire wash out issue.

I'm trying to get along with Pat here, we will make friends, whether he likes it or not. ;)

Pat's a big teddy bear... he just lacks the warm touch that Pred has :laugh:

And I'm not the best at expressing myself in writing so it's not too surprising that we got off to a bad start.

In any case, I'll update this thread with what ever I decide to do to this bike so other crazies who want to ride small bikes can learn from my mistakes.

Ivan likes everybody that he thinks he has a chance to snuggle with.

I think you may be confusing me not mincing words and having a dry sense of humor with me not liking you. I can't really decide if I like you or not until we meet face to face, or you do something to REALLY piss me off. I like Ivan even though he does stuff to piss me off because he realizes I know everything and am never wrong. Well that and he supplies me with a free link to Gomer porn.

 

[BigYZ]

we are now friends. Snuggling optional.

Gomer porn is the best investment I have ever made :)

me thinks the bike may have a problem, not a suspension badly setup. good tires? good pressure on the tubes? does the suspension compress and reboud smoothly? shock spring too loose or too much compressed? bind forks? nice bearings on the wheel and on the steering head?
if you are some what good with repairs best bet is get a service manual for the bike and start from there...

those bikes will never turn like a rm125 or any racing bike. BUT they are not that bad.

I'm with this.... have you checked all of these other things? I wouldn't expect it to be so terrible that you wash out in every turn.

My husband is 6'4" 235 lbs., and races a bone stock '06 CRF150F in a local hare scramble series, that has a "thumper" class (fun class for adults on air cooled play bikes, up to 150cc). He is obvoiusly much heavier than what the bike is intended, but he does quite well in the class, and hasn't considered doing stiffer springs or anything yet. Lots of the riders are on 150F's. Some have converted to CR80/85 or CR150R/RB forks, but this is an expensive conversion, and requires tripleclamp/steering stem mod, brake caliper mods, axle spacers, and likely still stiffer springs. BBR also makes stiffer "adult" springs for the 150F, and I think you can find them for around $70-90 an end?

Thanks, I've gone over the bike and everything seems solid and in perfect working order. I'll be doing some things before I ride again so I will take another look at everything.

Here is what may be a stupid question, would changing spring with out revalving be a bad idea? As you can probably tell from this thread, I'm not a suspension expert by a long shot.

you can put in stiffer springs, but the bike will start to feel like a pogo stick...as the stock rebound will be too fast for a stiffer sprin.

Thanks, that's what I figured would happen. Don't want that!

 

[scottiedawg66]

eh, i prefer a bit of pogo vs huge fork dive...either way getting the suspension set up will make or break a bike, espically for racing its always money well spent.

I have owned a stock CRF150F and ridden one with the BBR springs but only rode it once.

At the time I was 6' and 245+lbs. I did not have a problem with the stock 150 on the trails or even jumping small doubles (I know, it was not a good idea but it was fun as heck). The one with the BBR springs was pretty fun too and I really did not notice an improvement in the suspension other than when landing the small doubles it was smoother.

Cornering was about the same.

I rode the stock 150 in Charleston on some deep sandy trails and as long as I kept my momentum up and my butt forward (sitting on the tank basically) I could get it going at a surprising clip. I lost a lot of time in the deep whoops compared to my friend on the CR250 2-stroke but had a good time.

It is quite possible that you do not have a real problem with the suspension as much as you may have improper riding position.

The spring change will help but you won't notice it if your riding position is off and it is harder to ride forward on the 150 than it is a bike that fits your size better.

A friend of mine really want to get some 150's and race on this one small track locally that would be perfect for it. Small table tops and sweeping hard pack corners. It would be a blast for us old geezers riding some 150's!

These bike are a blast man! Before I got this I was riding a buddies CRF 100, an even smaller bike and stangely I hardly ever came off that bike. Over about 20 rides on it, I crashed maybe twice, and these were 5+ hour rides. Could just be a case of me needing to get used to the 150. I will definitely pay closer attention to my riding position from now on.

How wide of a tire can I put on a crf 150f front
