MOTOCROSS TO ENDURO CONVERSION

From http://www.crosstrainingenduro.com How to turn a motocross bike into an enduro bike or woods bike! Is it worth converting a motocross bike into an enduro bike, a GNCC racer or a woods bike? A motocross bike is very light, cheap, and has fewer things to break. And the extra power and firmer suspension might suit the experienced aggressive rider who is racing. But the light weight and racing pedigree of a motocross bike has disadvantages for enduro or GNCC racing. Motocross bikes aren't plated which restricts where you can ride them legally. In many cases you'll have a non o-ring chain, close ratio gearbox, small fuel and oil capacity, no electric start and that 19 inch rear wheel is more likely to get punctures and restrict your choice of rear tyres - not good for enduro, GNCC or a woods bike. And the race tuning and firmer suspension of a motocross bike can be a real problem for less experienced riders in the woods. So it all comes down to your budget, where you want to ride and how you want to ride. Some riders find that by the time they do their motocross enduro conversion they have wiped out any savings made buying a cheap motocross bike... and they still have a close ratio gearbox which isn't great on a woods bike. Then again, some guys just love tinkering and modifying so here are the usual mods to make an enduro or woods bike out of a motocross bike.
In this motocross to enduro conversion we'll look at mods such as a Flywheel weight, Adjust powervalve (some two strokes), Skid plate, radiator & hand guards, Lower gearing, Spark arrestor, Suspension changes, 18" rear wheel, O-ring chain, Auto clutch with higher gearing, Lighting coil, G2 Throttle Tamer, Two stroke - pipe change, Two stroke - head mods, Two stroke - low tension reeds.
My first impressions on Rob's motocross enduro conversion? Very very nice. Rob's mods have given the little 250 plenty of grunt and a very meaty midrange. I'd be tempted to put an even heavier flywheel in just to suit my style of riding, but love the engine overall. The YZ250 is known for great suspension already, but it's like a magic carpet ride with whatever tweaks FFRC made... very plush. You can see why they are popular in GNCC racing. Is it worth converting a motocross bike to an enduro bike? Sadly in most of Australia there are few places you can legally ride an unplated bike. But other countries like the US have plenty of GNCC events and places to ride an unplated bike. If you are on an extreme budget and can live with the compromises it makes a lot of sense. Or for the competent aggressive rider, it could be a nearly ideal solution. And of course some guys love a project bike and don't mind throwing money at something like this. But of course it can make far more sense to just buy an enduro bike then strip it back to save weight and put a lithium battery in it. Got any further tips, mods or suggestions? Let me know.
