The problem with buying aftermarket suspension it's a learning curve which can be both steep and expensive at times,in reality you could do with knowing at the begining what you know after some years,after market suspension is an addiction when you have got used to it there's no going back to production 'that'll do stuff',having spent years trying to convince a friend to buy some for his bike when finally succeding,he's that pleased, he tells me i should have been trying harder!!!
DD is correct about high and low speed ajustment,but Ohlins have only just introduced it on the the very latest TTX and that is not available for the Tiger(955) anyway,with Wilbers it's an extra and even then is only available if you pay for the optional reservoir to prevent overheating,i have Ohlins on my Tiger,1100s and Wilbers on a Ksport non has high or low speed ajustment.
Were we do differ is on the compression and rebound ajustment,if you going for an aftermarket shock(and the expense) i see no point in being able to control the rate of rebound on the shock when you cannot do the same with compression,because when you get used to riding with it, after a time beleave me you'll be able to tell the difference,even my wife can riding on the back.
Now this is were i hold my hands up and say i've learned from my mistakes,i've used Ohlins on my Tiger and 1100s for years,i bought Wilbers for my Ksport and didn't do my homework i assumed all aftermarket shocks came with separate compression and rebound!! clang!!!,having had the luxury with the others it drives me nuts that i only have one ajustment as on the stock shock on the Tiger,yes it's by far a better quality unit,but spoiled by me not doing my homework !!!,it's an optional extra.
Having said all that,as Ohlins for the Tiger have been unavailable for years,i'd still still look at at Wilbers as a serious option they are good middle of the road quality without the bells and whistles if you don't want them,and they only make them to order,so you have to specify weight/riding style so they come with the correct spring to start with.
