C50T or C90T
 

I'm going to buy in the next 2 or 3 weeks and have questions which way to go. I like both Bikes the 90 seems a little heavy for around town I was wondering if the 50 would hold up and ride comfortably on long trips(500 /1000 miles)? I will be rining one up no passangers and not to many extended trips.
Any information would be helpful.
