Bike crash ratio E=MC^2 blah blah

but also. you have riders who go 39 years without a crash. and some who go 1 year with 6 crashes.

also i havent put in the ages thing yet

What's the standrd deviation. I suspect your data is too erratic to be relaible.

**DingDong** · 20th June 2005, 17:31

moto-x age 7-16, 30+ crashes
road 16-32, 4 crashes
Beachracing 26-29, 4 crashes

total- age 7- 32, 38-40 crashes

Started riding when I was 13. Now I'm 15 and I've lost count of the amount of cashes I've done. On the motocross track I come off about 5 times each ride just from going to hard and losing traction. I've only had like 15 crashes on the dirt that were potentially bone/neck breaking though. I've only had 4 crashes on the road bike, last one was a doozy

yes indeedy it is
Im gonna say off by 1 year or so, purely due to the incostencies. IE. my source data is only from people who posted. there proberly is alot of people who didnt post who have never crashed or have crashed so many times that they didnt want to post. also some people might not include the 5k drops and some did.
I had 24 sources. avg riding years was 16.28 years avg amount of crashes was 2.8 (im rounding cos i left the data at work)
therefore. every 16.28 years there is 2.8 crashes
1x2.8 = 2.8
2.8 / 2.8 = 1
16.28 / 2.8 = 5.6
1 crash every 5.6 years

im proberly out a decimal or two cos im basing that entirely on my memory... which is shocking

edit. I was only counting road crashes as best I could. and I did count low speed incidents where they were available

Yeah you probably want to look at the SD though to see if the number actually means anything. I doubt it is significant to a decimal place.

Also, it wuld have been good to have a "Years since last crash" value, because I think I see a pattern of several crashs in the early years of riding, (presumably, this is an experience, lack of road craft/defensiveness thing) then settling down to a relatively crash free life for quite long periods. With an occasional "once in 10 years" sort of crash, which is probably just down to the fickle hand of fate

if I had good enuf info I would have a timeline of the riders and the amount of crashes. but its pretty well know fact that riders will crash more in the first 5 years than the second 30 years. well. actually I made that up. but it sounds cool. as someone had as their sig a while back %87.53 of statistics are made up

**pyrocam** · 20th June 2005, 18:27

oh and.
i dont know how to calculate it (SD)
could google it
but cbf

**Blackbird** · 20th June 2005, 20:02

... for the next 5.55 years on account of my last "off" being last month.

**Jantar** · 20th June 2005, 20:43

I started riding in December 1970. Crashes as defined by injury and/or damage, but not counting any while racing or off road.

May 1971. July 1972. December 1974. July 1976. June 1980.

So 4 crashes that count in 34.5 years of riding.

**Oakie** · 20th June 2005, 20:47

Started riding 1978. Stopped in 1984. One slight damage incident. Started again 2003 and no incidents since then. so ... 8 years, one incident.

**ajturbo** · 20th June 2005, 20:51

started riding at 15.. am 42 now, crashed every bike i have owned + the turbo the other day..

so that would be around 8 good crashes.. plus when i was racing the bucket i fell off every race and sometimes i fell off 3 times per race.....

OK mine's going to be a puck to work out.

In 1990 brought a 1980 GSX250 while in Backpacking in US. Rode it for less than 1month before dropping it on the 401 freeway in Toronto Canada.
When I return to NZ I got my Learners MC licience (1991) but did not get a bike.
Around 1996 got a GSXR250 for the wife (who had the full licience). Got the odd bit of riding in, but spent more time on that bike as the "Bike Bitch".
1999: I rode the GSXR250 from our place in Albany to Whangarei (she was in the "cage" pulling the Horse float). Started my nursing training in July that year adn used the GSXR as my student vehicle. Had my next bike accident later that year, but mangaed to get the bike repaired this time (got to love insurance).
November 2001: got rid of the Wife but keeped the bike. Took the 250 on my first SI Bike tour.
2002: Bike now my only form of transport. Get full licience and later that year trade-up to the VFR750.
Feb 2004: Last Bike accident I've had. I was loading the VFR on to the ute by riding it up a homemade ramp. Had not sercured the ramp well enough, and had the expected results because of this. brought "Roxanne" the CBR1000F with the insurance pay-out.
So far I have had no more Bike related accidents, but I can not say that this has been without the odd near-but-quite-accident happening.
Would be hard for me to work-out how many riding-hours I have had now or how many K's (done 15000miles in 1year on "Roxanne" alone) which would probably give you some really good bike accident stats.

**RiderInBlack** · 20th June 2005, 21:49

Sorry.
Short version. Start riding @ 27 but for less than 1mounth had 1 accident during that time.

Start riding again @ 33. Had my next bike accident @ 36. Last Bike accident I've had @ 41.

I am now 42 and counting.

So a ruff guess I've done about 10yrs on a bike now and had 3 accidents, but no major injuries.
