I have to ask and this might not be the forum but since many here have moved up to the K1600 I will give this a shot.
I have a 2009 K1200LT with 38,000 miles on it. I was looking at the K1600 Grand America as a next option. I went to my BMW dealer where I purchased this LT as a used bike a few years back ( I totaled my 99 LT so hence the purchase) I was informed by the dealership that they would not accept my K1200LT BMW on trade as it has the servo brakes. I find this troubling that a BMW dealer wont take a BMW bike on trade, I support my local dealership as I had lived in ND and had to drive longer drives for service so having one near me has been a plus.
This has been a big disappointment, Do many BMW dealers have the K1200LT black listed?
FIRST of all, do NOT interpret that this would be specific to the K1200LT - the same ABS system with servos (often called iABS) as been used on many BMW models between 2001 and 2006 (including the R1150 and R1200 Boxer models). Even the Police models had the same brake system (RTP variant of the R1200).
SECOND... I have heard "somewhat" similar refusal of trade-in but it was NOT as specific - in general it is more the age (10 years of more) OR the fact that there is less demand for a given model. For example, the so-called dual-purpose R1200GS are still much in demand, so the dealer knows that an older R1200GS (say 2005-2009) will be easier to sell than an used K1200LT.
FINALLY, I have no insight into your dealer's, but keep in mind the following facts (based on many years of maintaining / bleeding these ABS system):
- there is no parts available to fix these iABS modulator (neither from BMW of the OEM supplier who designed these). Although there is ONE independant ABS electronics specialist in Germany that does offer repair / overhaul service: https://rhelectronics.de/
- these iABS modulator tend to fail as they get older - even more so IF the maintenance / bleed schedule was not followed ..OR.. the motorcycle was left unused for long period (1 year of more)
- a brand new replacement iABS modulator cost is $US$ 2800.
- on these iABS with servos, when the Modulator fails internally (or has a fault needing an external fix - like a brake switch), you loose about 80% of the braking power as all you have is the so called "residual brake mode". You or the dealer cannot sell such "defective" motorcycle - furthermore, the dealer also has a large liability / safety issue on hand.
All the above facts, makes it clear that in many cases, a "potential" modulator replacement on a used BMW motorcycle (2001-2006 models) makes the buy (or trade in) a very risky proposition. You can easily have to pay close to the value of such used BMW just in repair (ABS modulator price + many hours to replace).
I have a feeling your dealer just knows that it is not worth the risk ;-)
