Reply to New double stroke design 11/6/2017 2:15 PM

this looks like a diesel two stroke - not petrol. Either way, potential for huge compression ratio to think about. In terms of forces / torque, currently the head bolts take a heap of force without making use of that load. So the second piston is trying ... more »

Surely, if two wheel drive ever takes off it will be once electric bikes take off. You could have a separate smaller lighter motor for the front (not necessarily in the front hub) and you could tune the level of power going to the front.

Suggest you put a 40 hr piston in this time

One thing is for sure - the legend of missing JS7 is growing. Will we still be asking in 2019? 2020? Maybe James wants to see how many years go by before the threads stop? Maybe James is starting the threads? Maybe in 2021 there will be JS7 "sitings"? ... more »

Reply to Is the glorification of Ronnie Mac good or bad for the sport? 10/24/2017 3:06 PM

I dont mind the character and the humour he brings. But sometimes he goes a little bit too far. So it isnt clear whether it is about riding or other stuff.

It wasnt that bad. But like Mathes said - move it to late Nov / early Dec and make it a preview to the next season. Nearly everyone will be there And create space for the MXdN.

"Find iphone" - already installed if you have an iphone. Just needs to be set up. Although maybe you need phone reception for it to work.

As long as he keeps out of the way when he is being lapped, thats fine.

Nice. This works in so many ways.

Shame. Edit: i mean its a shame in general terms. Not shame on him.

Reply to MX in decline in OZ or do u disagree? 7/1/2017 3:59 AM

That's a big part of the problem. Clubs, tracks, organisations all focus on juniors. Especially the ones being sponsored. But they seem to have forgotten where the money comes from for the industry. Kids on sponsorship don't know where the money for ... more »

Reply to School me on Mountain bikes for fun or training 6/24/2017 3:54 AM

My general comments, Find out what tracks are around and you are likely to spend most of your time on. Choose a bike that is going to suit riding those tracks. Assuming you keep at it, your first bike won't be your last one. So you just want to choose ... more »

That might be ok assuming it is new. But still maybe not the best deal around.

Reply to Sand added to Southwick 6/24/2017 2:32 AM

Lol. For a moment I thought you meant call herlings because he knows where the sand went (not that I agree with that view on Herlings).

Reply to Star power dominate rider missing 6/18/2017 3:36 PM

Ferris is riding better than he ever has. And is schooling a few big names over in Aus. Plus the tracks here tend to be similar to high point but not as big (wide). So not really an indicator of US speed.

Reply to Anderson's fast lap/used water truck lane 6/18/2017 3:27 PM

Back on topic, maybe for repeat offenders they should use litpro or something to check at the end of each race. On second thoughts, way too progressive for MX sports.
