Dirt bike helmet for motorcycle?




Skychan


I'm a casual dirt biker (though I have a proper MX dirt bike: 03 yamaha YZ 125) and I'm buying a motorcycle this spring. I've been told it's perfectly fine to use my dirt bike helmet (DOT approved).

Only I got wondering about wind resistance... At top speed of about 100km/h I feel a good amount of wind resistance when I turn my head sideways on the yamaha but I'm wondering if that might cause too much fatigue doing that on the highway at 120km/h while constantly checking the traffic.

I'm just wondering if a full faced motorcycle helmet might offer a noticeable decrease in wind resistance to prevent neck fatigue. I can't remember how annoying it was on my dirt bike.



Answer
Although a dirt bike helmet may be DOT approved, it should not be worn as a street bike helmet. Certainly, any helmet is better than none, but....I can only stress the importance of an actual street bike helmet. Street helmets are designed for a different type of impact. They offer much more face protection and eye protection.
A D.O.T. helmet criteria means that if it is dropped at a height of 6 feet and it doesn't crack...you have a DOT approval....great.....helmets not cracked, but your brain is a puddle of chocolate pudding. A snell helmet is also another type rating...does the same thing.
Buy a real helmet...a good brand name...spend more than $50 bucks. There are good helmets that are affordable. If you cannot afford this type of helmet, I understand, I'm not rich myself and can only afford what I can afford.
I work for a bike shop and I can tell you this..A NEW helmet in a box that is 5 yrs old is no good and has to be destroyed. We cannot sell them. There is a code in the helmet under the liner that will show you the date. Do not buy a helmet that is too near the 5 yr mark. This is when helmets go on sale at dealers. A 4 yr old helmet (new) maybe a good discount and still relatively safe, and affordable. You will get much less wind noise and fatigue with a street bike helmet.
Good luck...ride on....rubber side down..

What is the best bike I can buy for under $350 in your opinion?




aight


I have up to $350 dollars and I am looking for a mountain or hybrid bicycle.
f#%$ing bike people... I dont want to spend $2,000 on a bike...my car is barely worth more than that!



Answer
EDIT: I put this at the top of the page so you see it- NEITHER OF THOSE BIKES I RECOMMENDED ARE OVER $400.

Not $4000, not $2000, not even $1000. f#%$ing people that don't read answers after asking questions...

Maybe my answer was too long and it confused you. I'm sorry if I used words that were too long.



Let's get our definitions straight and maybe that'll get you your answer right away.

Mountain bikes are for riding on trails... you drive it to a site, take it off the car, ride it. When you are done you put it back on the car and take it home. A hybrid is a slower, more comfortable version of a road bike that may be taken anywhere there is a paved surface (including finely ground stone)... think of molasses compared to high fructose corn syrup of a road bike.

I am making the assumption that you are thinking of an ALL TERRAIN bike or hybrid. An all terrain bike is intended for a 50/50 mix (or so) of on road/offroad riding up to rain rutted dirt roads or worn trails. The reason I think this is what you want is that mountain bike pricing STARTS at about $700 and go up while ATB pricing starts at about $250 and end about $700.

Enough of the gobbledegoop. Regarding an ATB, you would be very hard pressed to find a better specced bike than a Diamondback Response. This model has been in the lineup since at least 1998 and has always been a very good value. As far as a hybrid you should, at the very least, consider a Diamondback Insight 1 http://www.amazon.com/gp/product/B005NXO62M/ref=pd_lpo_k2_dp_sr_1/183-5148203-8543663?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=lpo-top-stripe-1&pf_rd_r=0WEBV2MDFV98DM7T4HF2&pf_rd_t=201&pf_rd_p=486539851&pf_rd_i=B002LFRTTM which is available from amazon.com.

BEFORE I GET JUMPED ON, I am not backing too far away from recommending that amateurs NOT buy bikes online with the following:

Prior to ordering a bike online, get fitted to a similar model from a bike shop. Order the bike, then bring the bike IN THE BOX to the same shop for building. The labor will be about $50 and worth every penny. Then, go back to the shop for anything you might need such as helmets, bottle cages, fenders, pumps, and extra inner tubes. You'll both be winners.

The reason I am even suggesting this is because I have supreme confidence in the quality of Diamondback and Raleigh products. I don't think any other company is as careful about what goes in the box.
