Default Trouble code?

Got a ? about my 21 bob ive had sitting in my garage since its purchase in November, the bike only has 49 break-in miles. I got out once in a while to start it up, but the other day it acted like the battery went down, so i went to buy a battery tender. Just thought id give it another shot and it started up but then shut off. Again it started up and shut off, i noticed the engine light popped up, started it up again but ran this time. I cand go out and start it up and it runs fine, ran it through the diagnostics for any codes, got 6 codes, P0120, P0220, P1511, P1600, P1608, P2105. Ive got the bike on a tender now, and do plan to take the bike back to the shop ASAP when the weather is better. Just curious if anyone else has had this issue.

The first two are TPS1 and TPS2, third EFI Power Management Mode, 4th EFI Module Processor Internal Error / Watchdog Error, 5th Loss of continuous battery, 6th EFI Forced engine shutdown. All likely due to a discharged or weak battery.

If you don't ride the bike for more than a week or so, put it on a battery tender until it is fully charged. And don't start it occasionally. Starting an engine and not getting everything up to full operating temperature is doing more harm than good. As parts warm up, condensation forms and is left in the oils or collects in different parts of the engine and transmission and can corrode things over time. And, you really don't want the engine to sit and idle because it's just harder on things to run at low speeds for very long.

The battery may be ok with a charge, but I'd call the dealer and let them know what happened and that you are concerned about the battery and the DTC codes. Since you are in PA, you may not have a decent riding day for a while. So I'd be prepared for it to be in storage until the spring. I'd be sure the gas tank is full so you don't get condensation there too. And I'd put the battery tender on it every 10 days or so to keep the battery fully charged. If you get a nice day and can take it our for a ride longer than 20-30 minutes, that should be fine.

I have all the same codes on my 21 LRS. The bike sounds like a weak battery and a rough start to follow with these codes. Was the battery your issue?
