Does anyone know if there are centre stands of different heights. I have used centre stands on a daily basis with previous bikes, but I'm finding the GS very difficult to get on the stand unless I place plywood under the rear wheel - and this with height assist activated with gearbox in neutral. Gap between rear tyre and ground 40mm. I read people stating it is very easy, and there are plenty of YouTube videos showing people doing little more than standing on the lever. Any advice welcome.
