In addition, the R and X models of the 250 are fuel injected with a 4 valve cylinder head, while the 250F has the 5 valve head and a 37mm FCR carb. there are some differences in the bottom end of the engines as well. The big difference between the R and the F is suspension, the R has about 10ish inches of travel, the F has about 14.

Calling an illegal alien an "undocumented immigrant" is like calling a drug dealer an "undocumented pharmacist"
