Hey there,  my rear sensor is acting up and needs replacing.  Does anyone know if the sensor is the LSU 4.9 or LSU 4.2 type of sensor?

Hey mate, can’t tell you what type they are but I know Rollie’s keep them in stock and they’ll run you about $150. 

cheers... I'll have a look at then then.  Bloody pricey @ $150 though.

Replaced one of mine a while back tussuck , not sure what type they are but only id number on the box is 17014,

not sure if its any good to you?

If I remember correctly it cost me around 120 delivered after a search around on ebay.

Cheers...I removed the rear unit and the numbers on it are a standard Bosh LSU 4.2 device, so your right.  Your number is a LSU 4.2 as well.

I bought a new Thundermax autotune unit from a guy on gumtree for $250.It is for a 2011 Softail though.He still has 3 more. Hope that helps. Pm me if you want his number.Cheers.

Cheers matey.  I see the Thundermax ones are bloody expensive considering they are simple LSU4.2 units.  Is the $250 just the autotune model or the ECU as well?

It's the whole lot new in the box
