It was my son who got me back into bikes when he did his CBT at age 19 and bought a Yam R125 which was eventually written off. I bought an SV650 just so I could ride with him on a Sunday. He then graduated to a C90 (mine) and we had some good rides despite the disparity in bikes.
As he now lives in Australia it takes longer to organise riding together but the situation is reversed, I have a CT90 Postie and he has a SFV650 (learner bike!). TBH I think I will be shipping the Postie home and buying something a bit bigger out there to be able to keep up.
