After 27000 km without a sidecar? Wow, that's hard. My Solo has nearly 27000 km and the clutch is as new. I know only one case of slipping clutch (without using synthetic oil), that was after 50000 km.
On my sidecar-Estrella I'm going to change the clutch plates in about 3000 km, then she has 30000 km.
Major repair was changing the piston after 17000 km, caused by inadequate maintenance by previous owner. At that opportunity I also changed the cam chain and the valve shank gaskets (You should think about it also when you (let) change the cam chain).
Think it would be great to stay one week in Dubai, but I guess, 27500 km for each of my Estrellas wo'nt be the most
. Maybe the ways I've done with the sidecar should count double
. Or both Estrellas should be counted together. That would be 55000 km for my Estrellas
Another possibility would be the drivers Kilometers on Estrella
The highest mileage should have Stadtratte (Michael) I think. I remember something about more than 100000 km.
