The problem isn’t that you CAN’T start on a SS600 or bigger, it’s that it is easier/safer not to…
I don’t have a video, but I will try to explain why…
1. Throttle control is probably one of the biggest problems for a newbie…it doesn’t just come to most of us, it is a learned practice. In a panic situation, let’s say you are turning right (for those of us that drive on the right side of the road, otherwise left…) and start to pull out then notice a car barrelling down on you that you hadn’t seen, that is when throttle control becomes a problem…a newbie will become ham fisted and crank it to get out of the way…on a 250cc machine you will get accelleration and move accordingly, on an SS600 or better in 1st gear you will get a power wheelie, probably freak out, close the throttle and either wipeout or swerve all over the place…possibly be rear ended or run over…as a newbie you won’t be thinking “roll on throttle” you will be thinking “HOLY CRAP!! GOTTA GET OUTTA HERE!!”…
2. The problem with braking is in the slower speeds…parking lot or playground zone speeds…riding past a playground, a ball shoots out between cars across the road with a little kid in possible persuit…250cc machine has kinda wooden brakes and as a newbie again ham fisted four finger pull on the brakes…the bike comes to a quick stop and your heart is beating like you just ran a marathon…600cc SS bike has excellent responsive brakes and as a newbie ham fisted four finger pull on the brakes…the brakes grab immediately, the sport tires grab the pavement like glue…you end up doing a faceplant and sliding along the pavement with your 450lbs bike riding you like a surf board…
Would these things definitely happen, no, but they are quite probable as a newbie…we just aren’t expecting those types of reactions…plus on the SS bikes you would probably be going faster because the ride smooths out and isn’t so “twitchy” at higher speeds…
As for instructional videos…check out Captain Crash Idaho…he has some pretty good videos on YouTube…
It’s totally up to you what you buy, it’s just easier to gain experience and learn the skills on a less powerful bike…and the lighter the better…
Good Luck!!
Later.
