BikePilot , Jun 24, I think to make a modern trials bike from a dirt bike would be very expensive and extremely difficult to get anything remotely competitive. Maybe look into shipping a used trials bike home from the UK - they are surprisingly affordable in the UK. Have a close look at pictures of a modern trials bike - everything is extremely compact and it'd be rather difficult to get anywhere near that compact using dirt bike parts.
Just getting the exhaust right would require some serious fabrication skill, then there's the frame, major engine work you'd probably need to essentially make your own cylinder to get mild enough ports and a small enough intake port to work with an itty bitty trials bike carb , suspension you won't get enough steering lock with modern dirt bike forks - too fat , wheels rear needs to be tubliss - not too hard to do, but not free Back in the old days folks did convert bikes to dirt and trials, but that was before bikes got very specialized and they really weren't very good You could probably make something that wouldn't be too far off from say a Beta Alp or Gasgas Pampara by really stripping down a bike like the KDX and fitting trials tires.
A Trials motorcycle is just that, a motorcycle, ride what you've got. Here in the U. Things to consider modifying on a bike include, grind or cut the steering stops for maximum turning air cooled bikes frequently have more room than liquid cooled bikes , make sure very low gearing is available for the model you select as well as clearance for a proper Trials tire. Remounting footpegs can be very helpfull as well. I don't know what bikes you have available so I can't make any specific reccomendations.
Riding Trials is about mastering what you have, not having the same bike as the world champ. DyrWolf and jeffroman like this. I definitely couldn't ride a novice section in D6 on a non-trials bike.
Sure I could do the big obstacles then blow the section boundries, but the sections are way, way too tight for a big bike. I'm newish to trials so maybe not the best proof its impossible and its probably not , but it'd take someone very good at hopping to pull it off at the least.
Perfect for those that want a bomb proof wheel set. If you enjoy Touring, Randonneuring or simply want a more robust wheel our selection of heavy duty rims, spokes, hubs and nipples that will more than accommodate your needs. Single cogged asphalt or track wheels. Two people only? Not necessarily! Make sure the spokes from one side of the hub go to the holes on the corresponding side of the rim.
I know this is many years late, but I have just started to use a computer and can now troll through Cub stuff, to check, see and learn prior art Someone has used longer spokes, and this has resulted in a cross-4 instead of the original cross-3 spoke pattern, which therefore has the two spokes coming out of the opposite ends of the same slot being almost in a straight line, or at degrees, as you said.
Just measure the spoke lengths of the 2 wheels. The negatives of cross-4 are more weight because of the heavier longer spokes, with the attendant more resilient, flexing wheel to perhaps absorb more abuse, rather than a more rigid cross-3 wheel to aid riding precisionI don't know where the trade-offs between the 2 approaches lie since I am not an expert. I do note you are comparing the pattern of a front hub to that of a rear, which are probably of a different size, and therefore have different spoke lengths and angles.
I also suspect the drum-side spokes may be of a different length, so they may be swung in a different direction, rotating the hub slightly, giving the impression that the small spoke flange is fastened on out of register. You can post now and register later.
