My 4-stroke

(Click here to view the original thread with full colors/images)

Posted by: motoxracer1234---------------------

i have a 2004 honda crf250r and i have seen all those posts that the 4-strokes arent that good of a bike. I always heard that they take less maintenance then a 2-stroke but im looking and they are saying it takes alot. Also i saw that it is very very expensive to repair a 4-stroke so i was wondering if i should switch to a 125?

If you have been on a 250f I would not switch to a 125, you will be disappointed. The only change I would consider would be to go to a 250 two stroke which is what I just did. Went from a kxf250 to RM250.

Trail type 4 stroke bikes are low maintenance. Racing 4 strokes like your CRF are high maintenance bikes. They need frequent attention to keep the valves adjusted correctly, and have much shorter engine life than trail type 4 strokes. They are also much more complex than a 2 stroke, which makes maintenance more time consuming and expensive.

In order to build 4 strokes light enough to compete effectively with 2 strokes, they are very highly tuned engines, and the parts wear rapidly and need maintenance to keep them running correctly. The 4 strokes have some desirable characteristics, mostly in the power delivery, but ease of maintenance and the ability to neglect servicing your ride frequently isn't one of them, when compared to more mildly tuned 4 strokes or 2 strokes.

This is probably true . . . People who have only ridden 250f's would think a 125 is VERY hard to ride. However, they tend to be and feel lighter and corner better, and you can do a, AMA legal 144cc overbore to give it some more pep.
