I recently traded my Harley Davidson Iron 883 for an older Bonnerville recently, I already own a Harley Davidson FLSB Sport glide and really had a bad itch to own another Triumph, so I done a deal with someone and now have a Triumph Bonnerville air cooled 790cc in Cobalt blue sitting next to the Harley.

Well on the way home from Lakeside Harley Davidson I noticed that the back end skidded out a couple of times!, so not being far from my home I decided to ride it the rest of the way and see what the problem was?.

When I got home, to my horror one of the after marker shocks had spat out the retaining cover and seal and had been pumping oil all over the rear wheel, chain guard and swing arm.

So that was that, the cover got thrown over the bike, ordered a set of Hagon shocks as I trust this brand and have bought some shocks in the past and never had any problems with them. I waited patiently and the Hagon's turned up and being the ass that I am instead of cutting the grass and doing some work out the front that I had promised the wife I would do,I went straight to the bike to fit them :smile2:. I am lucky in that sense as the wife does not batter an eye lid, she used to ride motorcycles herself so shes know's.

I took the aftermarket shocks off and the dodgy one as expected feel apart. I fitted the shocks but one thing I did notice was that the lugs on one side is about 3mm shorter???? that between the swing arm and frame, now I looked for a reason why this would be the case, but there has been no damage to the bike at all, this bike looks like it has never been dropped or ridden in anything other than sunny days, I have had some mint bikes but this one is as clean as anything, the lugs look good and straight.

Has anyone had this????.

In the end I filed down the rubber grommets on the Hagon shocks, to make up for the 3 mm no big deal as they fit fine now.

Here's a picture of the Shock that fell apart, and no IT IS NOT AN OHLINS.

I would also be interested if anyone has owned this bike in the past, the original owner had WEB as part of this number plate due to his name, and being a Cobalt blue, it narrows it down quite a lot, the bike is a 2002 bike.

Look to be TEC shocks, cheap Chinese knockoff things. Previous owner probably put the stickers on as a vanity thing.

Wierd about the short tug. Is a lug short, or is the weld keeping the shock from seating all the way? It supposed to doesn't matter either way and effect is the same.
As pointed out they are not Ohlin's I spoke to Ohlin initially just to be sure, but I wasn't convinced they were Ohlins as they usually have a number stamped on top, so as you say stickers put on in vanity.

The lugs are not shorter, just the distance between lugs is, about 3mm enough to make you file the rubber retainers into an oval shape to allow fitting.

I spoke to where they come from and to honest they really wasn't bothered or seemed to care about it, to me this is a danger to life, so I wont be buying from them in the future. This is the shop the previous owner said that the owner before him had bought the shocks from https://www.tecbikeparts.com/

Yeah, as I pointed out.

Don't know what you mean by the distance between the lugs, but of course when you install the second shock you're going to need to lift the bike to get it to fit. Can't imagine why you need to shave a bushing.
Lugs as in the parts the each eyelet on the shocks go onto, the swing arm was dropped to its fullest extent, when I measured the distance, one of them was 3mm shorter from the middle of the lug on the frame to the lug on the swing arm.

There is something I have never seen before. A fake Olins shock. I have seen knock-offs in every field but not to the point of having what look like perfect fake stickers on the item. I would have fallen for that to be a real Olins if it was shown to me.

Its not a fake Ohlin's shock its a previous owners putting stickers on them, I didn't remove the stickers as they were coming off, Ohlin's were great in helping me identify that they were not Ohlin's and seemed very concerned about them until we clarified they were NOT ohlins.

The easiest way is to check the top of the shocks as they will have a batch number on them.

Ok - I guess I get it. Seems really strange for someone to do that?

From that one picture it sure looks like you got a clean bike!

Chinese quality at work.
Well this is the thing, I think these shocks to buy must of been around £100, I bought a pair of Hagon shocks for £178 including postage cost, to me the Hagons were cheap, but of a much higher quality, the same style shocks would have been three times the cost, but you get what you pay for, skimping on shocks, brakes or tires is just a no, no in my book, your life depends on it.

Filing the shock rubbers oval is a big nono in my book, rather depress/compress the swingarm to get the other one to fit. That rubber is destroyed now.

the swing arm was at its full extent, so no give on the swing arm, couldn't compress the shock, and I only had to file about 1.5-2mm each eyelet, so its not such a big deal, there was no way on earth they were going on otherwise.

Then that would have gone on first then the second one could be installed after

Trust me when I tell you, it was never going to happen unless I shaved some of the rubber out on the eyelet, I have worked on my own bikes for 27+ years, my friend is an ex Triumph tech, it was never ever going to fit without adjusting the rubber eyelets.

This is why I am asking why and how this could be, I have never seen it before in my life, even fitting that side first it would not fit, its like the lugs are closer on one side and not the other with the swing arm allowed to drop to its fullest extent. I only had to do this on one side.

Sorry but I don't understand this.......

Could you go through your fitting procedure in detail for me please. Personally I've never taken both shocks off to fit new ones so have never measured the distance between the frame lugs and the swinging arm lugs side to side. At what point did you do this with both shocks removed? You said 'swing arm allowed to drop to its fullest extent'.

I'm with @Twintorsk here if you really took rubber out of the centre of the bushing eyelets to fit them you need new rubber bushings......

Okay I put the bike on the centre stand and removed the old shocks, tried to fit the right side with a brand new shock, shock was 3 mm to long, tried to fit same shock on other side it fitted like a glove then with the other side I fitted other brand new shock, still 3mm to long (the shock), then I removed the left hand shock and tried to again fit right hand side first, guess what the SWING ARM still fully extended was 3 mm to short to fit the shock, fitted left hand shock, filled down the eyelet rubber on right side by 1.5-2 mm on each eyelet rubber ( on the shock )and it fitted. How else do I explain this?, with the bike swing arm fully extended it was still 3mm to short for the shock to it on right side but fine on the left.

so essentially with the bike swing arm fully extended we assume the swing arm lugs are both at the same point so I assume that the lug on the frame is 3mm closer to the swing arm lug than on the right.

As a previous poster alleged, those are TEC shocks (that someone put Ohlin's stickers on). Cheap-azz Chinese shocks that have come apart on others as well. Look them up TEC shocks coming apart. Avoid them (most of the TEC parts are fine, those, are not). Hagon's are the way to go (but just don't look as cool as the TEC shocks).

When I've changed shocks I've done them one at a time. I take one shock off and the swing arm drops some, and I lift the rear wheel to put the shock back on. This tells me that when the shocks are install the swing arm is not lowered to it's maximum.

In addition, I have installed longer than OEM shocks on my Bonneville. I've installed Thruxton shocks which I think are 1 centimeter longer than the Bonneville. They are definitely longer. This further tells me that the rear swing arm is not fully extended downwards when the OEM shocks are installed.

I have no idea why your shocks barely fit with the swing arm fully extended downwards. Either for some reason the swingarm wasn't all the way down or you have the wrong shocks. That's what I think.



The other thing I think is that I'd never buy a bike from someone to put a Ohlin stickers on Tec shocks. Only a wanker does that IMO. Wouldn't trust his ability to maintain a motorcycle, or his honesty.
