AWESOME is right JME!!!
As I stated earlier:I CANNOT RECOMMEND THIS MOD because of the mod required to the frame crossmember and I am SURE that I will get flamed from some of the nannies on this site BUT........
I REALLY LIKE IT!!!!
The ride AND handling improvement from the Racetech parts up front(I have 20w fork oil to replace the 15w(needs a little more rebound damping)) and the "upgraded" rear shock is FANTASTIC!
After a spirited ride on the winding country roads around here I realized that my back never once complained(remember I just broke it) and I found myself riding over bumps and broken pavement just for fun to see what it would soak up.
Front springs and emulators and oil ~$300
Used 2008-2012 Yamaha R6 rear shock $60
Shipping shock to Canada $50
Spring removal and reinstall $30
Labor........at least 10 hours,yes I took my time but I am an experienced auto mechanic.
It is also my hobby,so WELL worth it.
If anyone finds an easier fitting, equally good and equally inexpensive alternative please post it here.
To my knowledge this is the first documented "retrofit" of another OEM shock to a CBR250 yet.
REMEMBER: I cannot recommend altering the frame of any motorcycle
