  1. It's in the Pre 65 forum for two reasons, one is to provoke comment and hopefully gain some hints and tips, two is because it is probably more "pre 65" than most cubs you see! I freely admit that it's a cheat but is mainly ridden against modern bikes on the "B" route. Maybe we need a new category in the Forums called "Britshocks"!. I forgot to say that it also has alloy rims but I have retained the std cub rear hub which hasn't been widened although it does have an alloy brakeplate.

  3. Does anyone make an aftermarket tailpipe for the 250R?One that's easy to re-pack?I know of a couple of SY's that are fitted with modified motocross or enduro tailpipes but they appear to be a bit on the bulky side.I have re-packed mine but it wasn't a simple job as the pipe has a perforated inner skin about ten mill distant from the outer.The gap between the two skins is densely packed.You then have more packing material and then the perforated "through"tube.All this makes cutting the end off and replacing it a bit of a nightmare.Any ideas?

  4. Yesterdays No Stop Ralph Varden trial was one of the best trials I've ridden recently but being over 40,perhaps I'm biased!From a B route point of view,it was great to ride long sections,with a choice of lines.There was a decent number of riders and there was a noticeable lack of queues.Why would that be?!Nothing worse than watching someone who thinks they can trick ride five a section two or three times in one go and take a long time doing it!

    No stop is contentious but having ridden trials continuously for 34 years and having experienced the various rule changes over the years,I think it can only benefit trials in general.Yes,some people will disagree with me but I suspect a lot more will agree!No stop,if adopted across the board,will ultimately encourage fresh blood to trials because it levels the playing field somewhat.It will encourage an "I fancy a go at that"attitude,rather than a "blimey that's good"(but I don't think I will ever be able to ride like that so I won't be getting a bike).

    The vast majority of riders cannot trick ride,whether they like to admit it or not,so why not cater for the majority,not the minority?Of course,minorities usually make more noise and tend to get their own way!(Hitler being a good example!)

    The lack of entries in the World and British championships surely suggests that something is wrong.The danger is that lesser events will go the same way.Bike development will advance so much over time,that sections will become tighter and more outrageous than they currently are,so less people will be able to ride in the manner that will be necessary.Bike development influences section layout and influences the rules and vice versa.The vicious circle continues,until,like the Ouzle bird,trials will disappear up its own........

    Food for thought!I await comment!
