Forget everything else, invest in training yourself to ride safer and faster.
First up I just want to say that forget about having the latest BMW or R1 with carbon bodywork, tuned engine and so forth, don't get me wrong if I had enough money I would most probably get one. INVEST IN TRAINING YOURSELF.
I have done 2 sessions with Simon at Valencia and Almeria and it is without doubt the best thing I could have spent my money on. I started riding on track a year ago. I ride a reasonable bike with no aids and it has good tyres, brakes and suspension and I certainly have the enthusiasm and motivation to go fast. That said in my first year I had a big high side at Catalunya that resulted in broken bones and no income for 5 weeks....not something I can afford. After this I looked at what I was doing and decided that there was no way I was giving up but that I needed to do it more safely, gain greater knowledge and reduce my risks. This is where Simon came in. I'm a pretty intense guy when I want to do something and Simon is an amazing instructor and judge of ability that never gives up on giving you 100% of what he can. I have seen him work brilliantly with riders of all abilities, so whether you are intense (like me!) or not the best listener, nervous, scared or whatever Simon will work tirelessly to get the best out of you.
We worked together analysing my lines, throttle control, body positioning, braking and corner entry, corner exits and when to put power down, accuracy and bike placement, tyre choices and so forth. Then on track we worked at it until we rode behind one another like metronomes, going that little bit faster each time only when it was safer to do so.
On my last session (which was free by the way as Simon felt we hadn't quite got to the desired place with me and my tuition) it all clicked. Several consecutively fast and safe laps that lead to that state of euphoria that money just cannot buy. Destroyed slicks, huge smiles, big hugs, massive wheelies (from Simon) and John Reynolds in a very gentlemanly way saying that he could not keep up at the end which we all know isn't true :)
Whether you are slow, inter, fast or racer please book a session with this guy. I promise he will make you safer and faster and it will be the best money you spend at your track day. The MotoVudu sticker has pride of place on my bike now.
