  1. Not considering population density, 287 people per square kilometre in UK vs 38 per in USA and only 4 people per square kilometre in Canada. UK has 7.5 times the population density of USA and 71 times the population density of Canada. UK has exponentially fewer places to ride, not much relative distance to get to anything and a lot more trials riders. I seen a Jotagas once.

    TY 175 fork

    If only classic TY had teflon coated bushings in the lower legs to replace, but sadly they do not.

    TY 175 fork

    Triple trees limit your options to run larger stanchion tubes, the stock steering head bearing is the weak part. Steering head bearing upgrade to taper bearing is relatively inexpensive and gives you the most bang for your buck. ... if you could devise a way to run a fatter axle and larger bearings that would go a long way to stiffening the front end, it's not hard to twist TY175 forks. Super important to replace the stock wheel bearings frequently to maintain suspension and brake performance.

    st 125 2004 stator

    Simple answer is yes, stators can be rewound, very often by a local business that specializes in repairs to stators and starter motors.
  5. 4RT engine is the kind of engine you could run pinned for a long ride and not blow it up. They run a 36 tooth rear sprocket to make one more street worthy. 36 tooth sprocket will limit your Trials riding to mostly 1st. and 2nd. gear.
  6. Huge difference between the frames and sub-frame on those 2 models, 315 does not even have a subframe, fragile does depend on how hard you ride them and how often you crash it. Personally at this point I would not buy any trials bike that does not have a 4 pot front brake. Both are 2-stroke and would be horrible for the 20 km of on road ride in addition to a full day of trials terrain riding. Pre-mix fuel is going to be a problem for street riding distances greater than the normal 2 litre trials bike fuel capacity will provide. A 2-stroke air cooled engine will not have the fuel range or engine longevity you will get with a 4RT. Air cooled 2-stroke is going to smoke and rattle even more compared to a water cooled engine and adding oil to fuel reduces fuel octane making race fuel more relevant. Fat bars on newer models are less prone to bending compared to 7/8" bars with a crossbar support. KTM 2T enduro bikes have cheaper buy in and replacement parts on average, but they break lots of pegs, rads, exhaust pipes and plastics.
  7. The bike will be more prone to jerky throttle response in 1st gear, same reason you shift up a range on wet slippery muddy terrain, higher gear range with more clutch control will apply power to the rear wheel more smoothly and with greater range. and I suspect it is only a 125 and not 225 so there is not much power range to begin with so good clutch and throttle control is imperative.
  8. 4RT is the kind of engine you could pin for a while and not have a problem, very capable ride and user friendly as trials bikes come, carry a tire pump and pump up the tires lots for road use, let tire pressure down when you get to the riding area. You can get a saddle that can carry extra fuel storage. With a 4-stroke you won't be trailing a smoke screen on the road rides. Some of those motorcycles you are considering a fairly fragile considering trials bikes and hard enduro bikes are constant repairs and maintenance.
  9. With it being 10km from the nearest woods I would be looking for a Montesa 4RT, it's a durable bike that has been in production for decades and you can still get any parts. A 4-cycle engine is far better suited to the sustained road speeds and you still might even have some fuel left in the tank when you get there but if you don't you can fill at a regular gas station or petrol station or whatever they have where you live. 2 stroke trials bike on 10k of road just to get to the riding area would be brutal on both the bike and rider.

  11. Can you clean a gun? It's about the same but comes apart different. You need somebody that has serviced forks before to assist you the first time and from then on it will never be a huge problem or expense, I have assisted many in past years and they now do their own servicing, need to service one right now myself, a fork seal blew out this winter so I will service both sides. It's messy more than anything and takes about half a day once you have the parts. There are only 4 things that can be replaced in regular servicing, fork seals, slide bushings, oil and the spring if it is bagged out. Good parts to inventory because the bike is absolutely going to need all of them some day. Best luck with your service 🖖
  12. You posted to the general forum, might help more if we know what local is. Forks are something that need servicing so often it pays to learn how to service them yourself.
  13. You could maybe try unplugging the White to White/Yellow wire coming out of the engine. Diagram appears to show it as being a dedicated lighting coil output.
  14. Simple solution would be to simply occlude it. Black duct tape 😎
  15. I recommend a low cost clutch cover guard that covers the whole case (400$ part) and not just the bottom part and found the best way to keep it on is to use 2 sided tape instead of the bolts.
