Yes you can fit a dirt bike into a 6ft x 4ft trailer with the maxium dirt bike length being 7.07ft. This is achieved by positioning the dirt bike on the angle. Kids dirt bikes will not have a problem.
Being able to load a dirt bike into a trailer is a good solution for being able to transport you bike around.
In the UK a small trailer like this will come under the weight limit of requiring a trail license so as long as your vehicle has a towbar you can hitch up and go.
How To Tie Down A Dirt Bike On A Trailer
Use ratchet straps to provide downward pressure on the bike to stablise it. Use one strap up and over the handle bars, looping it around once before going back down the opposite side. Have another strap over the the back of the seat to apply pressure over the back wheel. 2 straps should be the minimum.
When trailer mounting a dirt bike you need to make sure you got it secure. One good thing about using a 6×4 trailer is your bike is likely to be very snug before strapping which will give it extra support, but no matter what trailer you are using make sure you use tie downs.
In addition to straps use some wood to choke the wheels to stop them moving as an extra precaution.
Dirt Bike Strapless Tie Down
If you use your trailer alot for transporting your dirt bike then you can consider a strapless tie down system for your bike with will do away with the use of ratchet straps.
A strapless system means buying a bracket system like the one from Risk, called Lock ‘n’ Load. These are brackets that you bolt into position and then wheel the bike into place and lock them to the bracket.
The system supports the bike in an upright position allowing for safe transportation and its very quick and easy to use. These types of units are excellent if you are going to the track regularly.
What I really like is the ability to take away the stand when you are not using it to leave the base plate on its own. This means that you can use you trailer for everything else you normally would. Check them out.
How To Load A Dirt Bike On A Trailer
Use wooden planks if your trailer doesn’t come with a door ramp, wheel the bike on and position the bike so the load is even on the trailer. If you have one bike then you want it centered, if you have 2 bikes, then side by side. Get the center of the bike over the axel of the trailer.
Making sure the bike load is spread as evenly as possible in all directions means the trailer is less likely to go out of control when being driven.
