when do the 2013 dirt bikes come out?

best electric bikes for 2012 image

Linda

im looking to get a new 250 dirt bike and i want to know when the 2013s come out. I am looking at honda, kawasaki, suzuki, ktm, yamaha...all the major brands.

Answer
All the bikes come out the same time, around the end of 2012. All the bikes are very similar, you're going to have to ride each of the bikes to find your preference.

KTM is way too much money, currency between Austria and the US isn't good. Yamaha is too advanced, their 2013 models are going to look like a futuristic robot, and it might even have electric start, which adds around 20 lbs.

Kawasaki is great as the 2012 model almost dominates the other bikes. I prefer the Suzuki, but it's all rider preference. Suzuki isn't over designed, it's the best bike in my opinion. Next years bikes could go from $8,000, but the KTMs... (Keep Throwing Money). Could go up to $10,000.

what engines are capable to run 100% on hho, h2, hydrogen gas for vehicles?

David Schw

Is there ideal engines for the conversion? I want to construct a van that holds enough hydrogen to operate 200 miles power day ++ and cover it with solar panels & a bracket to hold a1,500 watt windmill. Ideally,I would use an AC outlet to produce the hydrogen but with added options to make its own too. This is the ultimate bug out vehicle. I will probably wonder off into the wilderness forever once its complete.

Answer
Sounds like an interesting project. There are some car companies that make hydrogen internal combustion engines/cars but they are hugely expensive and conversions from gas to hydrogen has some problems. A propane engine design might be suitable for adaptation to hydrogen. The fuel/air mixture is much different for hydrogen requiring special carbs and engine timing changes and hydrogen embrittlement of engine parts or exhaust can lower engine life and other parts.
Storing hydrogen is another issue as it requires a large volume of gas under very high pressures to have a suitable range you're looking for.....special tanks, lines, valves, refueling, etc..

There are some new methods coming out to make on-demand low pressure hydrogen gas using chemical processes like sodium silicides or cobalt catalysts which could alleviate some of the problems with onboard storage/use. You can also make hydrogen from urine which has twice the hydrogen molecules as water and splits apart in electrolysis at lower voltages..
