Motorcycle Safety
	General Discussion This forum contains all general interest motorcycle safety oriented discussions.	3881	50901	* Today * 11:41 AM by: haithabu	Indiana Randy, Night Train
	Safety Gear This site is pro ATGATT and here is where you can talk about safety gear to your heart's content. It is okay to mention specific brands by name, but it is NOT okay to post commercial messages here. That is, a member can promote what he likes based on experience, but a vendor cannot post a commercial here.	70	521	08/21/2010 11:01 PM by: bachman1961	Axiom2000
	Ways to Influence the MIC-MSF via the Insurance Industry The MIC-MSF has a monopoly in the United States and therefore it is extremely difficult to influence its practices and its curriculum. Rather than attempt a political effort to do so, some think that obtaining the assistance of the insurance industry is a way to have a loud enough voice to cause some changes to occur. Here we can discuss ways of educating that industry to gain that assistance.	11	232	03/11/2009 7:38 AM by: SkootchNC	Night Train
	Rider Training Courses MSF (and other) rider training courses. PROS and CONS. There is no bias here. No commercial postings allowed.	276	4367	08/30/2010 8:24 AM by: Shadyrider	Axiom2000, gymnast
	Roadcraft Despite evidence to the contrary, the MSF approach to rider training is not 'all there is' or even 'the last word'. Here we can focus our attention on one such alternative body of training knowledge - one that is rather more intelligent and well considered than MSF's curriculum. England is the genesis.	22	381	03/07/2010 2:11 AM by: bachman1961	gymnast
	Sharing of Lessons Learned Every time we take our scooters for a ride we learn something. Share the knowledge here.	843	9844	09/01/2010 4:28 PM by: haithabu	gdickelman

How To ...
	Buying a used bike - is this a good deal? Here is a forum in which you can ask for and discuss used bike purchase questions like: Is the price reasonable? What else should I ask for? Can the seller REALLY have just installed a NEW stator on this 28 year old bike I'm thinking of buying? What this forum is NOT for is listing YOUR bike for sale.	4	28	08/09/2010 1:46 PM by: aidanspa	Indiana Randy
	Add-ons / Customization Want to make your bike a little different from the next guy's? You might find in this forum how our other members tackled the nitty gritty of making those changes.	93	508	08/08/2010 11:09 PM by: The Meromorph	Axiom2000
	Improve your skills Yep, parking lot practice is fundamental. But some of you have found other ways and may be willing to share here. NOTE: The first time somebody posts a HOW TO DO A WHEELIE OR STOPPIE post this forum goes away.	82	750	08/13/2010 4:13 AM by: Robus	dhalen32
	Preventative Maintenance Some kinds of maintenance (most, actually) should be done by trained professionals. But there are lots of things you can do for yourself. Here you can share the how to's with our other members.	27	241	07/29/2010 7:49 AM by: TonicBIA	Night Train

Models
	Critical Speed Calculator This model calculates the speed at which a vehicle will lose traction given the radius of a curve and the Coefficient of Friction of the roadway. This is usually called the 'Critical Speed'.	1	1	05/27/2008 11:38 PM by: James R. Davis	James R. Davis
	Lateral Acceleration & Lean Calculator Given the radius of a turn and the speed of the motorcycle, this model calculates what the lateral acceleration and lean angle of the bike will be.	1	1	05/27/2008 11:34 PM by: James R. Davis	James R. Davis
	Quadratic Equation Solver Whenever you can reduce an equation so that it takes on the following standard form: Ax² + Bx + C = 0 then you can use the quadratic equation solver to solve it. Note, there are ALWAYS two correct solutions for x!	1	2	05/29/2008 5:18 PM by: James R. Davis	James R. Davis
	Radius Calculator This simple model allows you to calculate the radius of a curve given the length of a chord and its middle ordinate.	1	1	05/27/2008 8:54 PM by: James R. Davis	James R. Davis
	Skid Distance To Stop Sometimes you just want to calculate how long a skid mark will be given a starting speed, the Drag factor components, and the assumption that you come to a complete stop without falling over or colliding with something.	1	1	12/13/2009 10:09 AM by: James R. Davis	James R. Davis
	Speed From Stopping Distance Calculator Used to compute how fast a vehicle is traveling at the start of a known stopping distance. It assumes that all braking is done with a constant deceleration rate (such as would generally be the case if skidding). It also allows you to include PDR (Perception-Decision-Reaction) time, if any.	1	1	06/19/2008 9:58 AM by: James R. Davis	James R. Davis
	Speed Scrubbed During Skid It is not intuitive, but skid marks do not represent speed. Instead, they represent energy transformation. That is, they represent the amount of kinetic energy that was converted to heat. This model calculates the amount of speed that is scrubbed during a skid based on the starting speed and drag factors.	1	1	12/13/2009 11:27 AM by: James R. Davis	James R. Davis
	Stopping Distance Calculator This model calculates the fastest possible non-skid stop time and distance given Speed, Grade, Coefficient of Friction, and Braking Efficiency. It also calculates the maximum decelerate rate possible given the height of the CG, length of Wheelbase, and weight distribution.	1	1	02/02/2007 3:08 PM by: James R. Davis	James R. Davis
	Vault Speed Calculator This model will calculate the speed an object (such as a motorcyclist) is launch at (in other words, the motorcyclist's speed at time of impact) given you know how far it is thrown, the difference in height between launch point and impact point, and the launch angle.	1	1	06/18/2008 12:01 PM by: James R. Davis	James R. Davis
	Lean Angle Calculator This model will calculate the lean angle of the CG of your bike given Speed and Radius. Given the width of your front tire it will also calculate the actual lean angle of the bike. Finally, it will calculate the maximum cornering speed that is possible with your bike.	1	1	02/02/2007 3:43 PM by: James R. Davis	James R. Davis
	Center of Gravity Calculator This model calculates the location of your Center of Gravity given as input the measured results of lifting the rear wheel off the ground.	1	1	02/02/2007 3:35 PM by: James R. Davis	James R. Davis
	Skid Mark Analyzer This model calculates minimum speed at the time brakes were applied given the input of skid length, Coefficient of Friction, Grade, Braking efficiency, Collision speed (if any), surface moisture (if any), and Transient Braking Time.	1	1	02/02/2007 2:49 PM by: James R. Davis	James R. Davis
	Speed Calculator This simple model calculates your motorcycle speed given the rear tire radius, final gear ratio, and engine RPM. Note that though you have to input seven values with this model, if you merely combined this model with two others (Rear Wheel Radius, and Gearing) you wouldn't need to enter anything.	1	1	02/04/2007 2:23 PM by: James R. Davis	James R. Davis
	Rear Wheel Radius Calculator This simple model converts the specification of your rear tire into the radius of the rear wheel. (This is necessary in order to convert wheel RPM into motorcycle speed.)	1	1	02/03/2007 10:50 PM by: James R. Davis	James R. Davis
	Horsepower Calculator This simple model calculates your engine's horsepower given its RPM and Torque as input.	1	1	02/03/2007 11:26 AM by: James R. Davis	James R. Davis
	Gearing Calculator This model computes the final gear and final drive ratios given the gear tooth counts for Primary Drive, 1st through 6th, and Final Drive as input.	1	1	02/03/2007 11:18 AM by: James R. Davis	James R. Davis
	Drag and Lift Calculator This model calculates the weight on the front and rear tires resulting from virtually all variables that could affect them in a dynamic state. In particular, you will provide static state configuration information then add such variables as Latitude, Altitude, Wind speed, and Temperature.	1	1	02/02/2007 3:20 PM by: James R. Davis	James R.
