Hi there I need some help with setting up my brand new Yamaha R6's suspension. Is there anyone you recommend or anyone who can help. It's currently sitting on a fully adjustable rear shock... too low I think its effecting its handling... Thanks in advance.
Give Robert Taylor a hoi....he'll be your best bet. The newer R6 has VERY good stock suspension, I'm sure you'll be able to get it spot on

''Fully adjustable'' has about as much credibility as Neville Chamberlain quoting ''peace in our time'' In truth the adjustment range is actually quite narrow and is a ''trimming '' device. The external high speed compression adjuster on those forks loses any worthwhile response if the low speed clickers are 8 or more clicks out, as by that time there is an appreciable amount of bypass bleed anyway.

You say ''too low'' A rude question, what is your personal height and weight? If you are outside of the range of what is considered suitable for the stock springing then you will as a very first step require different spring rates. Winding preload up on soft springs still means you have soft springs ( for example )

Pussy said these have very good stock suspension. Well in fact that is a term of relativity. Every year the pr guys state ''new, improved, race bred etc etc'' The reality is the suspension on stock bikes is built to a price ceiling with a finite level of performance. That is exactly why top level racers ditch the fork internals and rear shock straight away and fit top level and highly tunable components.

You will be able to optimise what you have, to a certain level. But your personal stats and application are relevant info for a detailed answer.

PM me if you want me to measure the bike up. From there you can talk to Robert about getting the correct springs for you.

Thanks Robert as always you are very helpful. I am 6 2" and weigh 81 kgs.

Okay, if you get Gavin to measure it and talk to me about the numbers. The spring rate in the rear may be a little light, if so Ohlins springs will fit. But in truth if you are going to use it for track days etc (and have the ability to open the throttle early! ) one of the biggest issues is that you will end up screwing the low speed compression clicker on the rear shock almost all, if not all the way in. This because the opening pressure of the internal shim stack is light. This manifests itself as too much acceleration squat causing the bike to understeer off especially the tightest turns in lower gears.

If this happens we can revalve and dyno test that shock. It wont turn it into an Ohlins but will still deliver a significant improvement. As we have a big database of Ohlins damping curves we use that as a very useful indicator of what we need to achieve in revalving the stocker.

But dont jump in and do this straight away, see if what I am saying rings true in reality.

With respect to the front it is likely that you will need to go up in spring rate.

Note that I am flying to Italy this Sunday 28th and returning 2 weeks later so will be unable to answer any further questions until I return

Robert, i think you might be getting a little confused. Raj owns a yamaha GP bike mate; gp bred .. Standard Road Ohlins won't help ;)

ps... hook me up with that Rear please kind sir and can someone in Auckland do the springs and re valve on your behalf..??

churr

* edit; Will you be at Taupo over thw weekend? specifically the KB track day.. would be good to meet you and maybe buy you a beer afterwards in return for the Ohlins goodness

Your cynicism is not lost on me! PM me as there are some further bits and pieces of news with TTX36 rear, I will have more specific info after returning from an Ohlins distributor conference in Italy.

Sorry, will not be at Taupo as I have a load of work to clear.

Thanks Gav for so meticulously setting up my suspension. The bike feels so much better now and just eats up the potholes. Havent pushed her too hard but I feel more confident already. I'll ride with the current suspension for a wee bit test it out etc... and when I plan on doing more track days wil get in touch with Robert for some springs perhaps? Cheers dude.
