Hi JohnE,
There can be pluses either way, and I will of course give you a 100% biased answer
The pluses of our bikes is this:
1. You don't have to worry about anything with the bike: fuel, transpo, tire wear, mechanical problems, zip. Just show up like a factory rider and ride. This can be pretty distracting, if a rider is concerned about his nice bike. Rarely do things happen, but they can. If that goes away using a rental--might be worth it.
2. Cost of repair. Even if you just tip it over in the pits (not likely, but possible) cost to repair is likely way more than on our bike (which only cost parts, no labor).
3. Our bikes are set up very well, really work nicely. That alone will give you a good comparison for other bikes (like your own). The suspension on your bike could be fine, could be a bit worn, could be not very well adjusted (we see that a lot). So riding one that is will give you a good standard to measure from.
4. Our bikes are taken care of by a top mechanic. Not only does he know the bikes, but all the different pieces of it: tires, suspension, riding (he's a top rider).
5. Racetrack riding is pretty taxing--you might not want to have to ride home after a full day!
Now, a plus of brining your own is you could have him take a look at it, and get some recommendations. But you could do that if you ride it or not. Some come and do 2 days, ride our bike one day, their own the next.
There you go, let's see what the other guys have to say.
Best,
Cobie
ps--I hadn't seen you post before, so welcome to the forum!
Thanks Cobie
