Was the CBR factory electronically speed limited at 186 mph? I know that my Suzuki Hayabusa was.

It was the last year of the carb'ed 900 series, the 929 switched to fuel injection so I think the electronics on the bike just ran the ignition, sensors and lights. I just stopped at that because the visor on my helmet flipped up. Right after, I pulled over on the side of the road and started shaking. Wont be doing that again.

Sure, but not a Harley "103."
For instance, would an Aprilia punched to 103" do it? Easy peasy.
Same for a Duc.
Heck both of these already push 180...

Lot of wise asses here because they freak if they go faster than 75 mph. Pansies. I got the Busa up to somewhere around 150 mph out on the Jackson Highway. That was my "fast enough..."

You should be able to get close to 120 mph, whatever that is in kilometers. The Fat Bob is a great platform for airing it out. Be careful and good luck!

I’ve only done 110mph and felt like it had plenty more, but I have no need to go that fast more than maybe once a year lol

edit: I’m on a 2015 street bob

120 miles per hour it's about all you will get out of a 103 stage 1 Street Bob.

Nice color on the 'Busa, is that a '07? Yep, 150 mph is just getting started on that bike! Had mine up to 185 mph one time (on a closed course, of course!), slowed down to 155 mph started to lift my head above the fairing...damn near took my head off, LOL! My 'Busa had I guess you would call a Stage 1...Yosh full 4 into 1 exhaust, K&N air filter, and Power Commander. Also lowering links in the back, 3/4" Genmar risers, and double bubble windshield. Later went +3 on the rear sprocket. Crazy fast bikes! Oh, and those front reflectors were gone just as fast as they were gone on my Low Rider!

Around 120 mph was what I was guessing for a relatively stock 103 Dyna...more than fast enough for this old guy, LOL!

I would save enough so you can do a cam/shave the heads combo. If going with a higher rpm cam, you definitely want to raise the compression and put in a 0.030 head gasket. That will do wonders for the power output.
