The little red bike in a sea of orange and blue...

Heck yea, the XR200 is still a very competitive machine for woods, desert, historic m/x.  Check out the pics and letter we received from our good buddy Al.


Wanted to give you a update!  Had a real good year in 2004 racing the XR200R.  One of the most interesting was on  Oct 17 when Jeff ran the LOBOS Heppner Fall Classic (80 mile high- desert cross country).  Entered in the +40 class with all the modern rides.  Ended up winning the +40 class and finished 25th overall out of 68 riders, and ran 2/3 of the second lap on a flat rear tire.  His first lap time was faster than nearly half the open experts second lap time........sure would like to have seen what he could have done without the flat.  I attached a couple pictures.......hope nobody laughed in the first picture as only one of them turned a faster first lap time, and overall he finished ahead of all of them.  Sure turned some heads to what a 46 year old guy can do with a 20 year old design 218cc 4-stroke bike!

Woodland has been good also, won the Unlimited Int. class in Dec against the big bores.  No race in Jan (ice) and we're getting ready for Feb 12.

 

Pete made the comment when we were down to see you that XR200's had won races against many larger bikes, YZ400's etc.  Tell him Jeff is carrying on the tradition, and also picking off the modern KTM 300's, 520's etc.

 

Be sure and tell everyone hello........and let them know  Team Old School XR is going strong!

 

Take Care!

Al P.
