For jumping? Not really
For charging? Yes
Smaller bike batteries have much less capacity, so it is important not to overcharge them. This can happen easily on a "dumb" charger designed for car/truck batteries when set on a high amperage. When charging lead acid batteries with "dumb" chargers, you have to estimate how much charge they have, know the AH (amp hour) capacity of the battery, and make sure you don't try to push more charge into them than they are designed to hold. Once charged, trying to push extra current into them will cause resistance to go up and up and create more and more heat. This heat can seriously and permanently damage the battery and can also cause a fire or explosion. It is also better to charge smaller batteries at a lower rate, like 1/10th the AH rate (which would be 1.2 or 1.4 amps) so the battery has time to actually deal with the incoming current. Also, charging a frozen battery is very dangerous.
The stock Concours battery is (or was) a YUASA YTX14-BS which is 12 AH (amp hours) or Furukawa FTZ14-BS which is 14 AH. So charging at a high level 2A, assuming it is COMPLETELY dead, the maximum time on a charger would be 6 hours (6h x 2A = 12AH). But batteries are rarely completely dead (and if left that way for a while it is sure to ruin the battery) so 4 hours would be a safer maximum at 2A in this example (or even better, 8 hours at 1A). Let's assume it was weak and yet half charged and you threw it on a big 12A charger (not recommended AT ALL), in just 30 minutes it could be fully charged (or ruined) so you can see just how quickly one could get into trouble.
Smart chargers which greatly simplify the process and increase safety need not be expensive. Here is an example:

Although I have a trickle charger for the Concours (Battery Tender Jr.) I don't have a regular smart charger for car (which often sits a week or longer without moving and then only short trips that don't charge the battery) or lawn mower. I have put that second link in my cart on Amazon (the Suaoki 4Amp)
