So, have done some miles with the new shock and it's a revelation! Initially the ride was still too hard but I backed off the high speed compression damping and it's now just right. The difference in damping quality has to be felt to be believed after the horrors of the OE unit! Having a damping adjustment that actually works is a real treat! I have mentioned previously that on a road I have to use regularly, there are transverse ridges which would throw me out of the seat with the OE unit, now, with the Maxton, I can ride over them without fear! They are still vicious, but the Maxton shock handles them without me resorting to prayer! On other, normal surfaces, the bike feels very composed, planted and neutral, without the understeer under power I was getting before, also very stable at high speed on motorways (highways), doesn't fidget as it did with the OE unit.
So a complete success and I can highly recommend the Maxton to anyone thinking of a suspension upgrade.
So next are the forks, which are now shown up to have poor damping. So when the bike is off the road for winter, probably next month, I'll pull them out and send them to Maxton for their cartridge upgrade and new springs. Can't wait until next year to feel the full transformation. Pix will have to come later, my IT arrangements are less than ideal!
