The Honda had over 60 f t-Ibs. of torque between 6500 and 800 0 RPM and it was plenty to get over the hill. So far as the corn ers go. square them off ! It 's qu icker . We frankl y d on't care what the ta nk of a moto crosser loo ks like or doe s so long as it hold s pre~m i~J preferabl y down lo w. Three HP is about 15,. more at top end and that's a differen ce. Each machine had at least t hree d ifferent rider s. You're wr o ng. Cooler is not better. To your next to last point, the CZ ad juster shafts are not too modern . . and we like funkiness. In starr opinion, the CZ rema ins a very desirable mount for the seriou s racer - the sta ndard of the 250 class. You obviously read into t he te st wha tever you wanted to .•.Ed.
