A little piece of advice from the geezers... 40+ crowd.
Let me start with a little back ground. I started riding a honda 50 mini bike when I was 5 years old and rode dirt until I got my road license. My first street vehicle was a Kawi LTD 440cc cruiser (before I bought a car). And purchased my first sport bike when I was 17... a 88 ninja 600. I was totally hooked on sport bikes and have ridden one ever since.
Over the years I have ridden with good riders and bad... but for the most part I have been able to hold my own regardless of who I was riding with. About 2 years ago I took an advance rider course and started doing track days... I quickly discovered, even after 25 years in the saddle, how little I knew about riding.
I was being schooled by guys with 1/4 my experience but they were smart.... they had professional instruction and learned how to ride correctly. I though about all of the money I had wasted on performance parts and tweaks I had done to my bike over the years. If I had just spent a fraction of the money on learning how to ride my bike, I would have been way faster and way safer.
Take a little advice from a recovering poser. It isn't your carb/exhaust/timing/tires/breaks/suspention that is making your bike slow. Start by upgrading the weakest link.... the part attached to the handle bars.
If you have ever though to taking an advanced riding course, doing a track day, or going to Pitt Meadows for closed course.... take the plunge and do it. Dip into the cash you had squirled away for the steel braided brake lines and learn how to ride. The cost will pail in comparison to the benifit.
Talk to Squire about heading out to Pitt Meadows track day or taking a course with one of the bike schools. If you are a noob to intermediate rider, it's time to take the next step because the world of riding will open up in ways you never thought possible.
Take it from me. Being able to safely carve out corners on a back country road is so much more fun than parking in front of Starbucks hoping someone will notice your shiney sport machine.
Hopeing someone will take my advice. Would have saved me 20 years with out progress if someone had told me this when I started.
