That looks like the one that finished earlier today near me in Lincoln. I was watching that out of interest as I bought one a few days earlier and wondered what the going rate was. Seems £521 +post for yours ;-)
New shock arrived today. Still struggling to see what's different about it as I can't find any info about the model number H0606-4 and it has a TTX sticker on it. It's too late to get it serviced and fitted by Monday, so I'll drop it off with Parkitt next week and have my forks uprated at the same time.
Well I've put the shock on now but I will need a new spring to suit my weight as its a bit hard for me
fitting was no problem mate wheel off shock linkage off drop old shock off put new one on the spring is for a 14 stone bloke and you feel it when your riding it as theres no weight to me [ 10/1/2 11 stone fully kitted out but it does look bling I didn't think mine needed serviceing as its only done about 3000 miles dry road use
Mine's been on a road bike for 2 years, but will be set up purely for track days. What's the code on your spring as I'm 14 stone geared up. Would be good to see if mine is a lighter spring.
I don't know mate forgot to wright it down now its on the bike I cant see it lol I think when they sell them new they come with 12.kg/mm [stock] spring as standard unless you specify your weight
Took mine to Parkitt today, they recommended a 110Nm spring for a 13.5 stone rider on the H0604 shock, but 120Nm on my H0606 TTX.
