Motocross

Well, due to certain circumstances I have to give up road biking Sad

.

But, I won't be giving up biking full stop. I want to start racing motocross. So naturally, I have a couple of questions:

1. I've got my heart set on a CR125, how much I be looking to pay for a decent one? (second hand).

2. What are the service intervals? I'd be changing the oil and filter after every meeting, but what about top end rebuilds etc?

3. How much are the rebuilds likely to cost me?

4. I will probably be going to a lot of tracks for practices so are the rebuilds going to be more frequent? (bit of a stupid question really, but there might be some variables).

I understand the great risk involved in this sport and am willing to take it.

I can probably blag a full set of MX clothing (incl boots and helmet) for xmas, but i'd like to have the bike first, wouldn't really want to be riding a Honda with lime green gear.

Cheers guys Thumbs Up

enduro is much better IMO, i got fed up with rebuilds all the time on my cr, plus you gotta fill it with decent oil all the time, your ment to service after every race but most people dont, as for rebuilds all bikes are diferent, i tended to do 6 races then put a new piston and rings in, if you leave it till it goes wrong then your looking at a hefty bill. there quite high maintenance. plus you gota do conrods, bearings, rebores ect.. proper crossers are good fun but the cost involved puts me off and im a mechanic so do all the labour myself, get a 4 stroke enduro and go green laning, much cheaper and just as much fun.. good luck Very Happy

PS: a half decent cr can be found for around 600 notes or a nice newer one for the grand mark. i just sold a 98 kx 250 for 600 notes, just had rebuild, new graphics ect.

I abuse my CR (last time i was out I blew a head gasket on a hill climb and just fed the leak all day) according to the manual you should rebuild the top end and decarbon the rc valve every 6-8 hours. This is crap all the 2stroke manufacturers have ridiculously short maintenance intervals. You should probably do the top end about once a month if you ride every sat and sun if not once a season is fine. You have to consider that most people dont do any maintenance for years and have little power loss. I had an instructer with a PHD in auto engineering and this guy would tape his bike and beat it until it popped (hey if you gotta rip it down anyway right?) 2strokes are so simple not much can go wrong. Especially a honda.

Is there a reason your heart is set on motocross ?

Have you thought about Track and Trail or Hare and Hounds ?

Surely it would be wise to start at a lowish level then build from that.

Reasons are many, mainly financial, mostly from a "pounds per mile per grin" .

IMHO full on motocross is better learnt from a very early age to be even slightly competative, these boys mean business right from the off

Go and watch you local club racers , totally dedicated nutters, Thumbs Up
