there are some old timers who are big bike collectors. they do not go around announcing their collection. these individuals have warehouses to store their machines and do not even ride them.
you either need a lot of time or deep pockets to restore classic machines in s'pore as we have crap support when it comes to classic's.
imho, there are minimal vintage machines left on the road and mostly what we see today, in terms of classics, are the remnants on the late 70's and early 80's if any. we do get the occasional machine from the 50's and 60's that they are indeed a rarity.
its great to see that there are still people out there who appreciate the older machines for their character and engineering achievements of that era.
parts and reliable/friendly/accomodating/not cocky/efficient mech's who can do the job has always been the true pain of a classic bike nut and I continue to believe it will be the same for a long time to come!
before getting a particular model, do check out on the particular faults of the machine to ensure that they can be sorted out. the cb's while generally tough bikes, which i love, have a chain driven primary gear, which requires you to completely split the crank cases to change.....
i know the location of a gpz1100 but it requires heaps and heaps and heaps of cash to rebuild.
the gs/gsx's are good machines to start a project on. you can still find some parts in s'pore.
