thinking of changing front to 19inch

anyone out there riding a 19/17 combo. I was thinking of also running tkc's.

I run a 19in with Dunlop K180 tires

Tell us more, me and a friend have considered a 19. Can you tell a difference in seat height ? How much difference in handling. Where did you get it. Iis cool !! Thanks in advance, Berwyn

yzf470

I race short track/tt so the wr250x was an easy choice to set up as a DTX bike to play on. You wont find clay tracks just anyware,so to get some laps in i made a street tracker.Wanted something other than a old sr or xs 500/650 brick to play on.
Tires are dunlop k180 19-18 wheels from Forest at wheeling.Blue hubs with blue wheels.I never did lower the bike was going to drop it about 6/7inches. Little slow to turn than the 17s but the k180 tires are about a cd5 so they slide good.

hEY DTX, THANKS FOR THE PICTURES, YOU GUYS BACK EAST LOOK TO BE HAVING BALL LIKE I USE TO 50 YEARS AGO. NOWADAYS THE EQUIPTMENT IS SO REFINED AND CONDENSED FROM WHAT WE HAD IT IS SO UNREAL. HAVE A GREAT TIME AND LET US HEAR FROM YOU ABOUT IT BUT JUST BE A LITTLE CAREFULL !! BERWYN

Had the yzf out on the ice earlyer this year.Bike was built by a retired pro,this thing can turn and burn like nothing i have ever ridden.
