TWN Contessa - Chassis

Handlebars

The handlebars on the Contessa consist of a central alloy casting with a short steel standard handlebar clamped to each end. I've seen at least three Contessas, mine included, with cracks around the clamping screws. The cracks on my scooter were two inches in length. All the area was vee'd out and alloy welded but broke again within days of re-assembling the scooter. After discussions with the welder we decided that the original design was incorrect in that it didn't allow the alloy to close-up and grip the steel bars. The alloy has now been cut through (see below) and the alloy casting rewelded - so far so good. This has been good for the past 18 months.
