Over the time ive been a member of KB i've noticed there are quite a few people who own or a fond of fzr,cbr,zxr,gsxr 250cc 4 cyl 4strokes, but there seems to not be much credible information on them,
On looking through some of my dads old performance bike magazines from the 90's i came across a test between yamaha's fzr250 and suzuki's gsxr250,the test has performance figures(dyno,1/4 mile,top speed etc),opinions on handling etc.etc

So since i was really bored i thought i'd share some of the info with the 4cyl T 250 riders,here goes....
