So I succumbed and bought another GTS300, the 2023 beige model.
I walked into the showroom intent on buying a light green one, but then saw this. It just had more class. Have had it for two months now and find it an absolute joy to ride. The re-designed front suspension has really made a difference. I think this model is the most beautiful Vespa ever produced, even better than the GS150!
Modifications so far - longer mirrors, remove side reflectors, paint transmission cover and exhaust heat shield gloss black, install 12-gram rollers, reduce slack in the throttle cables, re-design the rear numberplate layout, add a helmet hook under the saddle, replace front Piaggio badge with a red and black one. I will be fitting a topbox.
The performance is as good as my previous two Malossified GTS300s, maybe a bit better. The brakes are good but not quite as good as my previous Brembo/Frando combinations. With previous purchases I have always upgraded the front shock first thing, but I'm not sure this one can be improved much. I will wait for reports on the new Bitubo front shock when it becomes available.
