For faster road riding and track riding I would suggest linear springs are definitely the way to go though again make sure you get the right ones for your weight. Edit:See http://www.promecha.com.au/springs_advanced.htm "Progressive springing is much less popular for road-racing, with linear main springs used almost universally. There is a good reason for this: going around corners compresses your suspension, by quite a lot with modern race tyres. With progressive or dual rate springs, that means the suspension is going to be stiffer than when upright. However mid corner is also where you most need good grip and would really prefer your tyres not to be bouncing off the ground.""Dual or progressive rate springs are really a compromise that allows low-speed comfort without excess bottoming, which is why Honda fit them to road bikes. Racing is not about compromise, so they don’t get used for that."
I have just fitted K-Tech 0.95 springs with 2.5w oil, 140mm gap. Haven't been out on her yet but will report back once I do
Why choose such a light oil, K-Tech recommended me 10w with their linear springs, that's quite a difference?The oil was already in there - still fairly fresh from the previous 'RavenRider' fork mod that I carried out about 6 months ago.Anyway, after this evening's sortie, the 0.95 springs appear to be a little too firm / harsh for my lightweight form (13 stone inc. gear)...unless it's the thin oil causing the issues. Which it might be, considering Racetech & Traxxion charts indicate this spring rate is close to optimum (for me) Not sure now whether to plump for 0.9, 0.85 or just compromise with Hyperpro progressive springs...
Following this thread with interest. As a very amateur mechanic (read cr*p but willing to give it a go!!) how easy/ hard would it be for me to attempt changing the front fork springs and oil?I feel like my '02 thou could do with a 'sprucing' up and think that the suspension could be a good place to start.
