Africa Twin RD07 XRV750 - Engine Restriction Details

Because this post would have ended up being very long, I have separated the RD07 and RD07a into different posts.

There were a number of changes from year to year, so I will present the information for each year of production and provide as much detail as available to me.

Production years 1993 - XRV750P, 1994 - XRV750R and 1995 - XRV750S, RD07 750cc.

It would appear that the restriction modifications can be ascertained on engine number alone, but only on Austrian and German models. Bikes for the Swiss market were also restricted but their engine numbers are in sequence with the full power models, just to make things difficult.


Also, the Honda Area (Market) Codes are my best guess. Again, if you know better then let me know.

The situation is not as clear cut as with the earlier models, but bear with me and I'll try and make it as clear as possible.

I will start be listing the standard part numbers -

Camshafts, Part Nos, Front: 14110-MV1-000, Rear: 14120-MV1-000

Inlet Rubbers, Part No: 16211-MY1-000
