Reason MOCO went to TBW? Opinions?

[EdwardK]

ORIGINAL: Uncle Scrooge I guess that makes sense, butthe improvement would seem slight unless the bike's being driven by someone with palsy. Any hard numbers on the improvement? Is it enough to justify the added complexity and expense of the TBW? Complexity and expense??? It's simple technology. It's just a potentiometer that have been around since the beginning ofelectronics. ( i.e. volume knob on a radio ). Also, in the manufacturing process, it's cheaper and faster to install. It plugs in. No cables to adjust, no brass cable end to drop. Less labor to build the bike. You people should be more open to improvement. You used to get off the couch to change the channel on the TV bet I bet you don't do that anymore either. You spend ten minutes looking for that dam remote instead of using the dial. I love my TBW for 11,000 miles no. Works great!

TBW places the computer in full control of throttle......the twist grip is used for you to input your desires...the ecm then responds as per it's programed curves.

You can dial up wide open throttle, but bike will respond only as ecm allows.....ecm uses muli inputs to determine how fast bike acells/decells and will not allow bike to polute like with cables.

So the service manager at my dealership will charge me less to work on TBWthan on a conventional cable throttle?

Does anyone know why the MOCO went to the TBW system after 104 years of cable controls that worked perfectly well and which were cheap and easy to maintain and/or replace? It seems to me that having a simple cable system to force the throttle open or - even more importantly - closed rather than relying on a bunch of electronic/electrical components and connections is just plain common sense.

Well, I might have answered my own question right there!!

Anyway, any info is much appreciated.

If there weren't any technology advancements over the last 104 years, we would have to ride single cylinder, low powered, uncomfortable bikes such as the 1903. Drum brakes worked fine until disc brakes came out. Points/condensor worked until electronic ignition, ridgid front/rear was fine until suspension was put on, generators before alternators, etc.

You get my drift. There will always be change. It may take time before one is comfortable with it.

I've been thinking about this TBW system and it seems to me that all that's been done is to move the controller (a potentiometer) that provides input to the ECM from a location on the throttle body (cable actuated) to a location on the handle bar twist grip. It's only a wire extension, everything else is the same. Does this make sense?

As to why it was done, I believe it had something to do with space available.

Oh yeah, I rode my new, TBW equipped RG home yesterday and I couldn't tell the difference. It felt just fine!

Here, here! I often think Harley riders are a bunch dinosaurs just insisting the brand goes extinct. We will have no innovation damn it. I want my 20k bike to be an outdated dinosaur.

OK, with the same size engine and fuel injection system, how can the TBW enhance emissions and fuel economy?

I'm not going to deny that the part may cost more but the laborshould be less. It will be a lot easier to change. But then again, I bet they are both as reliable a

This is the main reason I do not like the TBW. I am all for advancements/improvements, BUT NOT ones that put a layer of separation between me and my bike.

I LIKE being able to turn off the fuel, I like having a reserve, I LIKE having a choke, while I would not mind having an auto tensioner for the primary...I LIKE having an inspection plate to be able to check the primary.
