or do you need a different helmet for a car race?

Racing or just driving? If you are racing you will need an SA rated helmet. This will differ from the M rated helmet (motorcycle) in that it is fireproof and rated for multiple impacts (the M helmets are tested for one impact). All sanctioning bodies for auto racing require SA rated helmets of the current spec and usually allowing the previous spec as well (SA2005 is the current, with SA2010 going into effect in Oct).

If you are signing up for an Open Track event or an HPDE or something similar, then an M2005 will probably be ok (the group organizing the event will normally specify the exact requirement, but I’ve yet to see any that disallow current M rated helmets).

This is a vintage BMW rcaing motorcycle starting and warming up. At AHRMA vintage fest Barber Motorsports Park October 2006. Sounds great!

i’m working on a project for my japanese class and i discovered Japanese street racing. However, most of the street racing is about cars, but my project is about motorcycles. So do street racers in Japan use modified cars more than they do motorcycles like Suzuki/Yamaha?

Thank-you!

It’s just as it is here in the US. There’s a market for both, but the market for street racing with cars is more popular and less dangerous. The only thing different is they’re more into drifting than drag racing.

We watch people on TV that stand outside in hurricanes and wonder just how crazy they have to be to do that? We see people in tropical storms getting blown down the street and wonder what kind of idiot would expose themselves to that? We sit back in amazement at the havocked reeked by minimal storms at a trailer park! Then we jump on our bikes with sleeveless T’s, tank tops, shorts and no helmets and proceed to drive at over 35 MPH (Tropical Storm) and 73MPH (Hurricane Category 1) and wonder why our skin is torn up.

There are products for the beach, there are products for skiing, there are products for bicycle riders, there are products for runners, football players, swimmers, etc…. So where are the products made specifically for motorcycle riders?

When Vance Lane of “Time Rider Shtuff for Bikes” offered to send me a few of their products to test, I was anxious to try their hand products for mechanics.  “Time Rider” is a website that sells quality motorcycle related products, with a sense of humor.  “Totally Awesome Crap” is a liquid glove and “Rub Dis” is Time Rider’s hand cleaner.achur) 

I used these two products while(more)

There is a ducati 900ss with 78 HP vs a 1999 Honda cbr f4 with 110hp. Who would win in a drag race?

Does more cc mean faster even though the horse power is less?

Tough question.

To answer your displacement question, more displacement does not always mean faster. The Duc is a V-twin (2 cylinders), which means it is slower revving, with a redline, depending on the year, between the mid-8000s and high-9000s. The displacement advantage, combined with the fact that each cylinder is larger than on even a similarly-displacing inline 4 engine, means that the bike puts out much more torque. But it is down on power, because the power of an engine is the product (think multiplication) of RPMs and torque. In other words, it delivers a bigger bang each time a bang occurs, but it delivers exactly one half of the bangs of a 4-cylinder machine per each revolution, and actually is limited to less revolutions per unit of time than the 4 cylinder engine (for various reasons, some straightforward, some more esoteric).

The CBR600 F4 is an inline 4 cylinder engine. Rev limiter kicks in probably around 13-14k for a 1998 (actual RPMs, not indicated, which are always inflated). The engine creates less energy per bang, but it has twice the cylinders, thus twice the bangs per revolution, and is able to reach much higher revolutions than the larger twin. Less torque and more power (again, torque times RPMs).

Another reason the Honda puts out more power is that it is water cooled, and the 900SS is an air-cooled engine. Water-cooled engines are capable of more specific power output because water cooling is more efficient than air cooling. Finally, the Honda has 4 valves per cylinder, whereas the Duc has 2. More efficient breathing always results in more power.

That was a rather long side track. Enough about comparing the power and torque of these two units. Back to your actual question.

Who wins in a drag race? Assuming the two bikes are launched with identical skill and reaction time, the Honda would probably win over a quarter mile. The Duc may well pull ahead from the line thanks to its superior torque, but the substantially higher power of the Honda would soon come through and catch, and then pass, the Duc.

Generally speaking, over a quarter mile, and all else being equal (identical launch, traction, and aerodynamics), the vehicle with a higher power-to-weight ratio will beat a vehicle with a higher torque-to-weight ratio every day of the week…and twice on Sunday.
