Hi, i'm riding TA 150 too, and my COE also ending soon. The bike still serving me very well and I think it still can tahan for many years.
But i wonder other cost like insurance and roadtax still be the same for 10 years old bike?
Out of bound for bike:
United Square.
But you can park your bike free under the carpark entrance. (The carpark entrance is a 'bridge' link to second level)
