All, is there a section or thread somewhere that lists exactly (models and year bikes) what other rear shocks fit the thou?
Do a search here's quite a few.
I need front and rear done for the cheapest price. My bike is probably only worth £1k so don’t want to spend nearly that to get it sorted, but I also want to ride it, as it is, it’s not pleasant as I can very easily find the limits of the suspension.
There's several that will fit but most need some level of modification. The cheapest would be get hold of a low milage standard shock, as it's a straight fit, next standard that's been revalved and sprung this is a gamble as it my not suit your weight. Fit R6, BMW shocks, those being the more common mods, or gor for replacement shock Hagon, Nitron etc these are new and range in price £300ish to £2500ish, or try and get one that's second hand between 50- 25% less.
Front end cheapest just rebuild what is there, depending on mileage, this could be just oil, or seals, bushes if you want it harder replace the standard springs £80 - £200, or get it revalved and sprung £200 - 800 ish, by the likes of Brooks or Ktech.
If you're up to it and have the tools. I'd recommend you strip the rear end, check all the bearings and rebuild it, same with the front. In standard form they aren't that bad, yes they can be improved but for everyday use it's fine. Especially if you're on a budget as you say you are.
