You ride a harley.... with a trailer you are the last person who can say anything about me and tuning, I've already proved that it doesn't need tuning anymore than it already is so I don't really care what you are saying on the matter
There's one guy Ian from the nameless place that I talk to on WhatsApp who does it, he's got a supercharged busa, though can't remember his forum name but it wasn't megawatt
I agree 100% a 200bhp bike for the road is completely ridiculous, there is literally nowhere that even half the power can be used, but and its a big but..... would you turn it down?
That does definitely sound excessive, I'd say the book is a typo it wouldn't take much to typo 105 to 150 I'd go with bike shop.
For reference the busa rear axle is 97.5nm so you'd be best not to go anywhere near 150nm unless your fine with a stripped tread at best
