Title: What Parts to Replace on Front Forks
Post by: Dirk_S on July 28, 2023, 08:47:35 AM: I’ve purchased and received a pair of NTX 650 forks to experiment with on my V7. Besides the fork seals (40 x 52 x 10/10.5) and dust covers (same as a Cali 1100, LM1000, and V7 Classic), I’m wondering A) what else I should replace as a wear item and B) seeing that only a few NTX 350/650 were brought to the US, I’m wondering if, should the exact part # not be readily available, any of these wear parts be able to be replaced with similar 40mm fork counterparts? Like…from the V7 range?

Yup, I initially start with TLMN or this site:

https://www.motoguzzi.genuine-parts-catalogue.com/moto-guzzi-motorcycles/650-MOTO-GUZZI-MOTORCYCLES/NTX/1990/NTX/FRAME/Front-fork/406/17/297001242/936 (https://www.motoguzzi.genuine-parts-catalogue.com/moto-guzzi-motorcycles/650-MOTO-GUZZI-MOTORCYCLES/NTX/1990/NTX/FRAME/Front-fork/406/17/297001242/936)

Unfortunately there are some parts that are NTX-only. Still cross-referencing and matching stuff like updated part numbers/replacements. I reckon a few of the NTX-only parts may be unobtanium, thus why I wondered if some V7 40mm fork parts can be used.
