I'm buying a 2000 Honda Shadow Sabre 1100 is it right for me?

I've been riding year-round now for 3 years never owned a car driven to Colorado from South Carolina and back I know how to handle bikes but I've never owned a bike this big my last bike was a Yamaha V Star 950 I'm going to step it up a little bit what should I really be expecting from this bike other than a bigger engine I weigh about 136 pounds or so 5 6 the 950 took me about a week to really learn how to handle before that was a V-Star 250 would this be a decent bike for someone like me

This is a fine bike. Get it checked by a bike mechanic. Ask for a discount if the tires need to be replaced. If you have some money, go a bit retro and get a 2 or 3 year old Honda CB1100. That bike is a thing of beauty.

What are you expecting from those extra 150ccs, slightly less weight and almost identical horsepower?

Plenty of opportunity in the last 17 years for mechanical abuse - look closely at servicing and at the seals on the shaft drive (especially if has been sitting for a while).

GOLDEN RULE: NEVER RIDE A BIKE YOU CAN't PICK UP.
