I have a new vintco crankshaft and main bearings in my 75 cr125m Elsinore and they are the "goto" company for my vintage motorcycle needs for sure. Quick turn around times and great shop folks whom i spoke on phone previous to buying crankshaft. You guys rock!

OEM Quality!

Great Stuff to replace hard to find originals!

Great AM replacement bearing/seal set

Good solid replacement, OEM is made of unobtanium apparently. Good fit, smooth bearings, great value.
