I gotta say ETR, and no disrespect, but what you're saying doesn't hold water. Karma John made a very good point. It's like buying anything used though, you just gotta be careful, my bike is brand new for that reason. But again, like Karma said, if you upgrade slowly you have to relearn your bike constantly instead of progressing your skill level. Of course, ultimately your skill level will improve, but in a much longer time frame, and with our short seasons I don't see how you can preach that??
I can understand where you are coming from, but would that not just mean the rider is a very slow learner? and not really the fault of the season? slow dosen't necessarily mean a month or season before upgrading it could mean weeks or simply the learning speed of the rider, i know and feel you on about the weather i wish it was summer all year but its not. yet i managed to learn just fine within the season, thats also because im a very fast learner, which then comes down to, the same thing i always say take advice from people to see what route would best suit you, because everyone has a different style and learning curve, which suits you best as a learner, if you look at all the famous stunters they are ALL different, they all have a different style thats why they each are famous, they all created their own way of doing things. I like knowing everything from start to finish, and i rather ride, on somthing i know is well built and i built, then something someone fixed up to sell and get rid off it dosen't mean so should someone else, its just something that someone else with the same concerns like mine might also consider. When you have been riding and driving semi-pro as young and long as i have you tend to try and not get into anymore accidents, because that is what really takes your time off the skill improving time, not doing things right and throughly the first time. Rushing into building a bike is just like trying to jump on a 600 with no riding experience, its a new territory, also when this all started the OG's of stunting who are famous today, didn't have fully built bikes from the get go, they slowly made new parts to make it easier to do their new discovered stunt move which they discovered, so they only invented these parts as they were needed, which everyone now buys before even knowing how to learn to do do the stunt and have anykind of use for the parts.
Your basis is like saying you can't stunt if you don't have these parts, while innovators think, i can do anything i want, and invent things along the way, back then people could do high chair wheelies without a finger rear brake, because they had crazy throttle feathering skills, today so many people have rough throttle control because they are too reliant on the finger break to stay balanced, because thats how they start learning, reliant on gadgets that make it easy for anyone to do a stunt that would make it easy by using it. The point is to be the best you literally have to be the best, and no add on makes the rider or driver only adds to making things easier. so not having all the parts right out is not the end of the world, but if someone wants all of it out the box, hey go ahead, people will do what they want, right?
I don't know if you ever herd growing up the sayings along the lines, people who try to make fast money loose it as fast because true success takes a brick at a time that flourishes into something that will withstand the test of time. Look up any successful athelete, actor, person they will all have one thing to say.
And time is not the only thing, one must have the passion and desire too, if season is a problem thats just an excuse, im still riding in november and i usually start mid march. 9 months is alot of time.
