JCR HONDA CRF450R AND CRF250R RACER TEST P68 so you want one that is super rideable and not grossly power- ful to where it has a big spikey hit. Sometimes that's really excit- ing and that's all good if you're riding it short periods on a track, so we try to broaden the power out and smooth it out through the range. We want to be able to ride first gear over super snotty, technical, rocks, and we also have to be able to go fifth-gear on a grass track, so we need real broad power that: one, won't stall; two, we can click it into fifth and hit 70 miles an hour if we need to." That same kind of philosophy goes into suspension setup. "Suspension, in GNCC rac- ing, a lot of the tracks have been raced on for several years now, forward and backward, and the holes are getting pretty big, and so are the roots and the rocks," says Campbell. "So it's kind of a tricky deal how to set up a GNCC bike, because you need the suspension firm enough to be able to go over holes and big dips and ravines and stuff like that, and whooped-out trails, but you also need it soft enough to absorb sharp rocks, sharp roots, in a very consecutive form. So, kind of the path that we use with suspension is, we need to ride up in the stroke, but we need it to react quickly, like high-speed quickness for the rocks and roots to where it's not getting knocked all over, and you're not losing traction. On top of that, we can't have it bottom in big G- outs and holes. So it takes quite a bit of tweaking. Bones (Jim Bacon) at Pro Circuit has helped us with that, with suspension settings. "Our 450 has been in devel- opment for two years and now I feel like we have a really good winning package. Chris proved last year that he can win; overall it's coming together." Campbell says that setting up bikes for Baja and bikes for GNCC racing are two completely different animals. "Setting up a GNCC bike is quite a bit different than Baja," says Campbell. "Baja was kind of easy for us in a way, because that is the type and style of rac- ing I did growing up doing and that came second-nature to me. Bach's CRF450R Honda is built for speed and comfort.
