Report Alpina 250 76mm piston in Bultaco Posted October 12, 2019 Hey, new here. I just picked up a model 85 Alpina 250 and found out the piston was a 76mm. Anybody ever seen this? Seems like a huge jump from 72mm. The piston was cracked when I got it. Anybody know where I can get another one? thanks in advance. 1
