It is the distance between two points of maximum compression (or minimum compression).
Here are a couple.The compression force of that machine is measured in tons.I was amazed at the compression force I felt.
They form a compression wave.
2 examples of compression are a child's pogo stick and a cars shock absorber .
Speed.
depends on the year, i have a yz250f 2006 and its GREAT! if your trying to get a 2011 i would get the crf.
A YZ250 is much faster than a CRF250r. The YZ250 is a 2 stroke where as the CRF250r is a four stroke.
They have 5. Owner of a 2007 crf250r
95mph
A bit of a trick question. A stock crf250r would run in the 65-70mph range.
A CRF250R is a 4 Stroke bike.. And the CRF250X is a 2 stroke. E.g one has a power band and the other does not
110mph +/-
339
No the 2010 model does
Yes
8.4:1 is the compression ratio for 04-07 STi's.
about 80 mph +
