Another sprocket question

[Louis Angel]

Does anyone know if this chain & sprocket combo ----> http://clevelandspeedshop.com/collec...and-cyclewerks

will work on this bike ----> http://www.motobuys.com/lancer-enduro-250.html

Everything I read about the 200 & 250cc Dual Sports says they are not geared well for the street. I am going to have to re-sprocket mine
for maximum street ability. My understanding that D.I.D. sprockets & chains are of high quality.

If not, would someone who has been down this road before be so kind as to point mi in the right direction as to what would be the best sprocket to get. Need to maintain long runs on 60 MPH. ( 30 min. drive, twice a day, at 60 MPH )

THANKS!!!!!!!
