What sprockets do you have on it stock? Both sprockets should have the tooth count stamped on them. 75 mph is asking a lot out of a little motor unless you're 110 pounds like Azhule. Keep in mind, none of these bikes were meant for tons of open highway use. Regarding the speedo, maybe Ski Rush can chime in. Is it digital on that bike?

I live a stones throw from the Canadien line in NY State. I drove a Ford dump truck with a kph speedo. I just multiply the km reading by 6 and ignore the last zero. For example 60 kmh X 6 is 360. Ignore the zero and you have 36 mph. Yes, I know you are supposed to use .62 as the multiplier but I'm not smart enough to do that in my head while driving...ARH

I do agree though, 75 is a tall order for most of these bikes. My bike is pegged to get there and screaming away at 8000rpm. Sustainable and repeatable highway top speed would be a more realistic 65mph with the right gearing, but you do sacrifice some off road capability to get it there. Most of us are unfamiliar with the DB36 since the dual sport version is so new. I will try to figure out what sprockets the bike comes with and do a little gearing math to try and figure out where it is stock, and what options are out there.

its 14teeth in the front and 37 or 38 in the back I can't see any scores on the gears indicating what teeth they are

slap a 17T front sprocket on it and 60-65 should be no sweat. The Brozz with a 17/39 stock gearing cruised wonderfully at 60mph.

If I remember correctly, the DB-36 runs with a 520 chain setup, so a 17 tooth would be huge lol.

So, after adjusting for the difference in tire size between your Deluxe and my Hawk (I also have a 520 setup). I can make some comparisons.
I currently have a 13 front 35 rear on my Hawk, which on my bike is the equivalent to the very common and popular 17/45 in a 428 chain that most Hawks tend to run. This setup is capable of hitting 75 on my not very stock bike at 8100rpm. I don't tend to go there very often, nor do I ride for any real distance at those speeds. Instead, my bike happily sings along at 60mph at 6500rpm, and 65mph at 7000rpm, which it will happily do for the few miles I ride on the highway while on my ride to work. With your shorter diameter 130/70-17 rear tire, in order to match this you would need a 34 tooth rear sprocket paired with your 14 tooth front. Otherwise, stepping up to a 15 tooth front (assuming it will fit and it exists) and pairing it with a 36 or 37 tooth rear will also achieve the same basic result. Assuming these sprocket sizes exist, from there it is simply adjusting the teeth counts until you would achieve what you are after. a 15 front 35 or 34 rear would get you close to what I consider the most highway friendly gearing that doesn't entirely neuter the acceleration.

That is really cool it's 520 out of the box!
