Biking Washington State

Vespa ride in Washington state.?
I have a Vespa ET4 and I'm thinking of riding to Lake Wenatchee State Park Wednesday. Stevens Pass will go on I wonder if anyone has done this on your scooter or if it's a death wish on my part. my bike is a 150cc and can do 55 in an abdomen 65 + upwards and downwards. any advice or criticism are welcome.
Not a good idea. The smaller bike ride was in that route would be 250 and even that would be a great risk. Among unskilled drivers and RV drivers truck ruthless record, never had a chance, even if you got on your shoulder all the way ..
