187 is the model, you can google it.

Yes, no problem. 1976 / 77.  Alpina 250.  Bore 72mm X stroke 60 mm = 244 cc.  Great bikes, if mostly complete, get it. O.K. ?

Was the Alpina a trials bike

 Alpina was essentially a Trials bike modified for trail riding. The true, and superior, Trials model is the Sherpa T.
