    Nice ride home from work, going west on Ginninderra Dr. At the set of lights that if you turn left you head to UC College/AMF/Maccas, and the cable snapped at the change to third gear post-lights.

    Fucker snapped in the exact same location as last time, right up top leaving less than a cm of cable attached to the brace; at least I made it ~300m further along GinDr this time ...

    Joe's fixed 'er up last time, but it looks like they gave 0 fucks as to why a throttle cable would snap with only 12000 kms on the clock. Seeing as it's been another 10000 kms and she's snapped in the same place, I'm gonna replace the cable myself and actually look at why it's snapping.

    Besides rubbing and uneven surfaces, anything in particular I should be looking for? How long should I be expecting a throttle to last?

    Would have thought it'd last more than 20000 kms; might start carrying a spare in the tool kit ...

    Should really last the life of the bike. 50, 80, 100,000kms not 10 or 12,000kms. It has to be badly made and be rubbing on something. It should be free to snap back when let go of the throttle.

    Could just be the cable - a plain inner into a wire-wound outer will wear our pretty fast unless lubed very regularly. Teflon coated conduits with good solid teflon and a thicker inner might be the go. There's a multitude of universal throttle cables out there which are DIY options (just need a soldering iron).

    It could be routing, too. Hyosung might not have taken the best care so it might go through a weird angle, promoting rubbing of the inner on the outer. So, ya replace it as per factory spec and it does the same thing.

    Have you lubricated the cable in any of that time?

    Oh yeah, another thought, it might be that the throttle tube lets you pull it beyond full throttle at the EFI, which stretches the cable. Some housings should have a throttle stop to stop you doing that, because if you're pulling several degrees past full throttle at the throttle body/butterfly end you may be overstressing the cable at either end (the weakest point and where it turns the most angle).

    Note: not implying 'you' as in it's an operator error thing, more a design issue.

    It always (well, did) snapped back nicely. There is definite colourings to indicate wearing; especially at the spot where it did indeed snap.

    Gonna see what I can workout when I get a new cable.

    Still ticked that Joe's didn't care to have a squiz when replacing the first time ...

    Tbh, if something like that happened to my car, I'd be on the mechanic that looked at it once the long weekend's over.

    You've probably already done this but:
    1. Identify where it snapped;
    2. Look at the snapping point to see if it was consistent rubbing (flat, blunt around a part of the snapping point) wear that snapped it or if it was a tension snap (frayed all around edge of snapping points) - that might tell you a bit more; and
    3. Chew the mechs ear off and demand a replacement ;)

    In both cases, the original and replacement, it looks like the only lube they'd seen was what came when packaged. I also wasn't sure if I should be lubing the cable or not so didn't; I now know better.

    Having a look at the assembly, there isn't too much that should be causing excessive wear, however until I get the replacement I won't know for sure.

    Interesting what you say about the over-pull and stretch as that is something that had come to mind. The assembly does indeed have restrictions to stop the cable from being pulled too far, but it may not be correct to cable.

    It's always had a bit of slack in the throttle when rolled off; causes a bit of jerk to the uninitiated.

    As you've suggested, I get the feeling it's a mix of cable quality and Hyosung design quality ...

    I was imaginary chewing the mechanics ear off last night when it happened, trust me! Haha

    As for the suggestions, I have indeed done those as I waited for my brother to come and pick me and the bike up last night:

    1. It snapped about a cm away from the knob on the top end in the throttle assembly.
    2. On the assembly, there is colouration that indicates wearing which is at the exact point of snap, however the snap is a distinctive fray of the cable wind. I haven't had the chance to check for flat wearing on the cable yet.
    3. When I go to pickup a new cable from Joe's, I'll be in a right mood. They're probably so sick of me and this bike; the shit they've had to fix for free is amazing. Such a Monday bike ...

    You buy a Hyosung, then blame the mechanic when it breaks... interesting.

    Don't be too hard Rob, truth be told they're not bad bikes at first impressions. But...I agree, I personally am glad not to be on one.

    Maybe you should consider a sell/change to something Japanese (or Italian #NotBiased) OP

    Hahaha touché

    I haven't blamed the mechanic for what was wrong from factory with the bike; I blame the mechanic for the parts they use and the work they did/didn't do

    I bought the bike based on international reviews, and others I know with Hyo's who have had no issues with and love 'em.

    As a bike, and more specifically as a bike for someone on their plates, it has done its job.

    But yes, come late April when I'm off the plates I will be test riding everything I like the look of and assessing the next ride.

    But with a second cable that seems to have a defect.

    Amusingly, I am quite smitten over the thought of getting a 07/08 VTX1800 ...

    As I've previously stated for the topic, I think the issue is with the assembly; there is an aspect that is causing excessive wear and tear.

    My issue with the mechanic is that they could have had a bloody look before fit-and-forget. Before commencing work, we discussed the fact that it had snapped at such an early stage of life.

    Meh, whatever, gives me a chance to learn more :)
