Bully fanatic it's amazing how similar our approach was. I also had a "dual-purpose"

Alpina that I did the similar transformations on between riding to work/Uni and riding Trials. I didn't swap tyres though, because the only trials tyres I could afford were Bridgestone "Trials" tyres that were fine on the road. I remember my 325cc model 99

Alpina being capable of scary-fast riding on dirt roads with the road gearing on it. One day out near "Honda" Hill out behind Ferny Grove I had the great pleasure of cruising up that hill in great style on that

like it wasn't even a hill. Honda Hill was so-named either because

s were the only bike that could get up, or because

s were the only bike that couldn't get up, depending on whether you liked

s or not. My riding and high-school buddy who showed me where Honda Hill was on his

RL250 was an accomplished Trials rider and also had no problems on the hill. Fond memories.
I do remember having lots of trouble riding Novice grade trials sections on that model 99

Alpina though the reason for that had little to do with the bike, actually because I was a total Novice Trials rider.
The timing of our

Alpina escapades were not quite aligned though, because I had mine in 1975/76. It would have been two or three years old in 1975 when I bought it for $450 and while it ran, was fairly run down. By the time I sold it, it was a good thing and looked quite nice.
The next

Alpina that I was aware of was bought new in 1978 by my friend Darcy Redman. It was his model 212

Alpina. Darcy was a senior TAFE teacher at the newly-opened Mt Gravatt TAFE College. He came from somewhere up near the Bunya Mountains and had been involved in the running of the early Bell State School fund-raising trail rides when a popular bike for that area was the

CT110 because it was light and low geared. His model 212

would have been like a Superbike to ride after a

CT110. I learned a life lesson from Darcy Redman about

s vs Japanese bikes but didn't know it was a life lesson until about 15 years later with the advent of Twinshock Trials and P65 Trials. The lesson was about why he bought a new

Alpina when I had bought a new

IT175.
