If you ever wanted a leading axle for your 250R's front wheel it's not a hard modification and one that Team Honda had used in the past for certain tracks. (although they had access to "custom" parts)

the 83/84 250R's use the same diameter forks as a 85/86 350X.

by swapping the 250R lower legs for the 350X's lower legs you'll now have a leading axel. As an added bonus you'll go from a single piston brake caliper (250R) to a duel piston caliper which inturn will provide more pad surface area and result in stronger brakes.


Why would you want a leading axel???

Well first off you will lose some turning ability. whenever you lengthen a machine this will happen. Also by putting the wheel in front you increase the rake.

the benefits of this are...

a lot of people like to lengthen thier trikes by modifiying thier swingarms. this can be expensive and dangerous if not done right. or they buy a new one. very expensive.

plus after you've modified your swingarm you'll need at the very least a stiffer shock spring and possibly a new shock. adding more expense.

a longer trike tends not to wheelie over backwords as easily

so if your looking to get a couple of inches ( the actuall amount is aprox 2.5" ) added to your 83/84 250R this is a cheaper option.

I was considering doing that to my 86 200x, but my 350x forks were bent and I didnt' feel like taking them apart and putting in the guts from my 84 250r front end, I probably could have used the bottom part, but why go through the trouble. I used a 350x tripple and 84 250r front end, I also cut the steering stops back to where they almost hit the tank, It turns almost as much as my short track 250r. Also, don't know if you know, but 85/86 250r front brakes are identical to 85/86 350x's with the exception the 250r's have cooling fins. Now to get a cam for that bike and install my terry kit.

not exactly.

85 350X front caliper is the same. and has the fins

86 350X uses a slimmer caliper and does not have the Fins
