I used to work on these, they are crap, just spend a few more dollars at your local yamaha store and get the real thing, better yet go to a good scooter dealer and buy a vespa, stella, bajaj or an aprilia, if you buy a diamo you will constantly be taking it back to the dealer for repairs and when the very short LIMITED warantee is gone count on spending aprox $200 to $1000 per year. Just doesnt make sense to buy something that will fall apart if you use it and loose 2/3rds of its value the day you buy it does it? The yamahas vespas etc hold their value, must be because they are made by reputable companies.
