Welcome to our recently updated Classictrial web pages. Primarily we are involved with upgrading and improving the performance of the later and more competitive twinshock trials machinery, but can also help with various alterations to older P78 twinshock and P65 type bikes.
As well as modifying existing machines, we manufacture and supply a small range of high quality specialist products for Fantic and Honda, which have all been proven in serious competition conditions.
We have also included some general technical information here, which may be of assistance to anyone who is quite new to the sport, and this will be added to on a regular basis.
There are also some contemporary tests of twinshock bikes, which make interesting reading in comparison to some “tests” of more modern machinery. You will also find some contact details for dealers who can help with twinshock parts, as well as providers of various specialised services, whose details can sometimes be difficult to find.
As well as offering a reasonably wide range of upgrade options for later twinshock machinery, we can also assist with steering geometry alterations and footrest relocation on most twinshock machinery (inc P65).
We are also able to supply OKO, Mikuni, and Keihin carburetors set up perfectly for any trials application, and can supply fit and jet a carb on your particular bike, if it’s a machine we do not already have set up data for.
All parts and services supplied by ourselves have been thoroughly tested in serious competition, and the Classictrial chassis alterations and OKO carb upgrade used on his 300 Fantic, helped Phil Wiffen to win the 2008 ACU “Traditional” twinshock trials championship.

We can also assist with improving the older and more collectable type twinshock machinery. However the modification of these types of bikes if they are still in original condition, is something that needs to be carefully considered, as its only too easy to reduce their value, if any major alterations have been made. Conversely it is certainly worth bearing in mind that the cost of upgrading any earlier machine to be anywhere near as competitive as a stock 240 Fantic for instance, can be extremely high and may well result in a bike that has cost more than £6K, and may well be worth less than its build cost on the UK market.
Ongoing development of new products is very important to us, and while we are unable to help with the very costly billet aluminium items that seem so fashionable at the moment, we are currently looking at the feasibility of producing modern type plastic replacement air boxes for Fantic, that will be less restrictive and of higher capacity than the OE parts, that should be ideal for anyone wanting to fit a 249cc motor into a 240 Professional chassis. The performance of the 249cc motors is drastically reduced if a 240 air box is retained, and finding a good condition 300 Professional air box is now very very difficult.
