faffi Posted September 6, 2012 Report Share Posted September 6, 2012 There used to be a time when slides were predictable, like digging parts hard enough into the asphalt to level the wheels off the ground or whacking the throttle open at maximum lean. But 10 years ago, I began suffering from slides erratically and unexpectedly. Over the last decade, this has eaten into my confidence. Example one: GSX600F Katana, fitted with Dunlop D204s (or was it 205s?), had great grip wet or dry on asphalt. But on worn tarmac, it was like riding on marbles. Getting slowed down, steering and cornering became precarious, dramatically different to what it was on other surfaces. Braking distance at least doubled. Example 2: Same bike, but now with BT45 front and ME550 rear. At first, the rear would just slide out with an inch of chicken strip, scuff marks about 90 degrees to the rolling direction clearly visible. I cleaned the rubber and sanded it, but it didn't help. With time - and lots of slides that saw me play dirt tracker on dry asphalt - the tyres gripped better, but the final 1/4 inch stayed unused save for the marks left from the slides. A later fitted SuperVenom didn't slide. Example 3: XT600 on Pirelli Scorpions would slide the front or the rear or both at very shallow leans at times, especially near interesections and on on-ramps. At other times, it would lean to the point of no chicken strips without a hint of slip. Then I fell off. Example 4: VT500FT on ME330 front and ME77 rear. Behaves very similar to the XT600 in that I may have great grip around one bend and then sliding at much less lean around the next. Very limited grip in the wet, feels like skating, almost. Tyres have been little used, but are old. But I've ridden on old, hard tyres before. They delivered consitently poor grip and where hence predictable, unlike these items. Example 5: CB400SF on D253s. Again, these unexpected slides at moderate leans, from both ends. Very soft suspension. After adding oil to the fork for more air spring plus fitting stiffer, but still supple, Hagon shock absorbers along with a Nankang sport touring tyre I've not had further slides. So how do one deal with this? My old KZ650 on cheap rubber works fine, but the other day riding the VT I decided that the tyres would stick and just relaxed and rode it through an intersection. Only to have both tyres slide. The XT slid there as well. So all these slides - plus I've hit a lot of sand, mud and manure all over our roads lately - makes it really hard to ride even with a hint of briskness. I really need to work out why this happens, what cause them. Suggestions? Quote Link to comment Share on other sites More sharing options...
