That's where it varies by location. Some OTD prices include all taxes, title applied for, and registration paid, others don't. Even where it is the norm to pay those at the dealership, they are often willing to accommodate selling a vehicle with no taxes collected and handing you the Manufacturer's Certificate of Origin or having it mailed to you. This can be advantageous if you buy the motorcycle in a different state than where you intend to register it and have it titled. The best way to get a low OTD price is to drive your car to the dealership, trade it in on a motorcycle, and then leave with a big smile knowing you left with it paying less than MSRP
MSRP is meant to include some margin of profit for the dealership, problem is that dealerships have largely had low numbers of new units show up the past few years. Without much new inventory many have either jacked up their prices to make similar revenue with less supply, or they've adapted their business by buying more used inventory to sell, doing consignments, selling more merch and accessories, selling electric bicycles and scooters, etc. A couple hundred bucks might be worth not having to wait to some people. $1,500 extra sounds like something I'd certainly pass on. There have been some decent prices on low mileage used CT125s on the classifieds section of this forum, another option for securing one without the wait.
American Honda only raised the price (freight surcharge) $100 for 2022, the rest is at your dealer.
