Have some classics in the stable, which I drive little but sometimes, and there is a red oldtimer change mark. With this you can drive e.g. to oldtimer events, make test drives etc. Makes sense only with several bikes in this status. Before now a review has to take place (§23). Question: Do there apply the same rules as with H-marks for car oldtimers? There it says for example, that the paint must (for example) have the original color. Have here three wheels, with the following Beso changes: 1. Machine has grey painted engine covers, which were original aluminium-silver. 2. Tank + side lid repainted plus a decoration (under clear varnish). 3. Accessories exhaust (scheibl, contemporary). Is there any problems with the report to be expected?
