Bargain Paul, spend a couple of $100 with it rebuilt and you'll never look back.
Good chance a suspension specialist will be able to adjust the stroke , revalve and respring to suit your the trx ratios and your weight.

You think it's good now mate, you'll love just how fine you can tune the suspension. 8) 8) 8)

Relay arm and swing arm length all come into play with progressive ratios and damping / spring rates.
Even if your mate on the gsxr is the same weight as you and had the shock built to his weight, you will find the spring rate will be too soft. It will be even softer once the stroke is reduced by 12mm.

I looked at the Penske shocks for a mates 900 hornet I did some work too, but the Wilbers ($1050)had the same options for a little less price.

Same goes with the R6 shock, if you weigh 80-85kg if your on the R6 , the spring will be too soft due to the longer swing arm length and relay ratios.
But the shorter trx swing arm length and different ratios makes the spring rate stiffer for a TRX.

Lucky man Paul , great score, sell the R6 set up and it will cover the costs for the rebuild ( but you may onlyhave to pay for a spring) 8) 8) 8)

Fantastic looking bike,The colour looks the best.The side on lines look spot on
An Observation,something has never looked right with the standard trx position of clipons in the fairing 'gap'
On your bike ,the side on view shows the clip-on height to be 'central' with respect to the fairing.
On a standard TRX he clip ons look too high or the fairing looks low , maybe we should all use upside down forks like you did or jack the fairing up

So never really got happy with the Penske I had on the TRX, the spring rate was far too high for my weight (I am only 75kg) so I was never able to get the sag and damping right

I was thinking about getting it serviced, re-sprung and re-valved but decided to get a new custom shock from Nitron instead

Thanks to the Brexit impact on the pound it was pretty reasonable

It is fully adjustable and all that and was custom built so should be pretty good.

Once I have had a chance to try it out I will report back but expect good things

I'm delighted the decision of the masses made the Niton more affordable! 8)

Fitted it this evening and set the sag. Left the damping settings as delivered.

Mighty impressed so far.

Had a short ride home from the mate's place where we put it on

1. From his place, there is an uphill right-hand bend with a change of surface and bumps mid corner which previously use to cause the rear to bounce out and the bike to want to push wide. I didn't even feel it.

2. The rear is squatting less when I accelerate and not coming up as quick when I brake so the bike feels flatter, I am used to a pretty big weight transfer between accelerating and braking so I will need get the hang of that change. I noticed this braking and accelerating the lights on Victoria Rd, which has a decent surface and a 70km/h speed limit.

3. Also on the way home is a street I hate. Harris Street is usually a nightmare. It is really bumpy and was very harsh and uncomfortable. It has a 50km speed limit and I used to have to lift my bum off the seat on a couple of stretches and the bike was bouncing around. This was so bad that there were evenings where I took motorway (toll road) just because I was not in the mood to get knocked around. Last night, Harris Street was still bumpy but the bike didn't bounce around and I wasn't uncomfortable.

So far so good. Need to take it for a good trash out of town to see how it performs but all looks good

Have you got a link to where you purchased the shock from?

Thanks in advance.

I ordered it from Demon Tweaks, they provide a very good service and show prices in AU$

I might have a discount code at home, I will have a look tonight

Nitron are good, but in the UK we`ve got plenty of folk who make good stuff:

http://www.protechshocks.co.uk/

http://www.shock-factory.co.uk/

And of course the VERY best Maxton:

I have Ohlins on the TRX and a Maxton on the TL, the Maxton is BY FAR the better bit of kit. :wink:

My Shock Factory shock looks really well built & the delivery was super quick. Looking forward to seeing what difference it makes

I'd be keen to hear your opinion once you've had chance to get it dialled in.

At the moment, I'm leaning towards the 'budget' option of an R6 shock which would run me about AU$250 with all the bits I'd need. A 'purpose-built' unit from the likes of Shock Factory, Nitron, Wilbers etc is going to be closer to AU$650 by the time I've shipped it to the land of plenty. I'd be curious to know if my ham-fisted riding style and general lack of ability is going to notice that extra AU$400.

A 2006 R6 shock will be ALL an average rider requires if you have it set up properly for your weight and style. ;)
