Handles are quite small

I bought these handles for a Hudora Scooter L205, because they are cheaper than the original handles from Hudora.
The handles fit very well. However, the grips are very small, you may therefore have large hands. For our 8 year old son it's just yet, but in a year or two palms of his hands will be greater than the handles. The original Hudora handles have significantly larger grips.
