I just got back from the local Suzuki/Honda/Kawasaki dealership. A 2008 Burgman 400 is going for about $ 6000 and they only had one. Ay caramba! The salesrep also said that Honda has stopped making the Reflex series in 2007. The only large scooter made by Honda anymore is the Silver Wing series. Yamaha has stopped making the Morpheus.
So for large scooters, it seems that only the Suzuki Burgman, Honda Silver Wing, Yamaha Majesty and TMax are all that are available from the Big Three manufacturers. That would be 400, 600, 395 and 499 cc, respectively. Wow, I had not realized my choices were so narrow.
Maybe I'm misunderstanding about what you want, but what is it you'll be doing with a scoot that can't be accomplished with 150 or 250cc?
I've been pricing scooters lately, and looking at the MSF course. The Kymco 150s are about $2600. The Bajaj are a bit lower.
seems like the scooters manufactured in the PRC seem to enjoy a fairly low reputation. Geely and Janon are two of the best known brands, and reliability, parts and service seem to be a nightmare. I have read a lot of posts from people who bought them via eBay and complain a lot when they need work
The local scooter guy says he'll service any scooter that wasn't made in China. He has some of the Bajaj, which are made in India. Can you imagine how bad the PRC bikes must be when Indian technology is greatly superior?
