  1. I’m not surprised the parts went quickly, given the size of the used quad bikes market!

    Hi do you have the cdu250cc engine?

    1. Unfortunately, we don’t have a CDU 250 engine at present.

  9. Random question. I can’t find the answer online. I’m going to be buying one of these to work on, any idea what the weight limit is? I’m a big guy, want to make sure it can hold up.

    1. It should be able to, I’ve seen them on farms and building sites being ridden by big (16 to 18 stone) blokes whilst being loaded up with stuff.
      Unfortunately, I don’t have any official Honda data for the load capacity.

    Hi guys Are you able to give me a price (roughly) for what a 2002 Honda Fourtrax 350cc manual petrol 5 gear Quad is worth?

    1. It depends really if it runs or not and the working hours/condition etc?

      Your best bet would be to have a look at sites like Auto Trader, Ebay (completed listings) for similar models to get an approx price.

  15. I have a engine for my old 2003 350 and am looking for the unicorn Honda shell with a blown engine lol what years will that engine fit it
