We (wife with her bmw f800gs) just got back from a month long m/c trip to california. 8000kms total. Montana, highway 37 along lake koocanusa is beautiful, the cascades highway through idaho and washington is also awesome especially washington pass and fairly quiet. Camped all over, mountain lakes, coastal cliff in fort flagler washington, redwoods in cali. Highway 101 and 1 all the way down to san francisco for 2 days and stayed at the fancy international mark hopkins hotel (it was in the movie bulitt!) Highway 1 is narrow and insane and fun all in 1. Relaxed in san jose for 4 days at a friends acerage up in the hills and got a tour from him of google. Monterey bay, then lake tahoe. I couldnt wait to get the hell through nevada, no offense if you live there bit its kind of a dump...interstates, 125hp and 85mph made that much more liveable. We did utah last year so we just did some mild exploring on the way through. Jackson Hole to Beartooth pass!!! Almost 11000 feet. Its crazy. So much fun, 8000kms over all and a honda st1300 loaded like a pack mule that didnt miss a beat! Now, oil change , diff oil change and spline lube with moly60 and a wash!
