I was told the oil cooler of choice back in the day for the TT1 was an item from a Citron 2CV maybe someone could confirm or deny this
Anyway ended up with 2 of these somehow no use now open to offers if anyone can use it cost me about Euro 30 still in the box

Hi Ducfan, yes this would be one of two coolers used. This cooler was used with the TT2's as the subframe mounting brackets match the mounts on the cooler (inboard). The TT1's used an IPRA cooler with AN fittings. Similar to the coolers used on the 750 Paso. Different mounting bracket. Outboard fittings. The TT1 subrame is also a little bit longer so the fairing is about an inch further forward. I think this has been covered before. I was just working in the garage mounting an IPRA oil cooler on an ORSP subframe. What a pain. It would be easier if the oil cooler mount was pre bent before being welded to the subframe. Oh and I'll take the cooler if you would ship to me. PM me the total you want with shipping to NY 11577. Good luck, let me know if you need and more info. Thanks. Lou
