I'll teach ya! It'll be as good as we get until we can race with Bernhard (Gartenzwerg) in the Alpine cup, then we can truly get our bums kicked!

..if the track is not too rough, I bet the better driver will make the difference

The M5 is still a surprisingly capable bike, it's just too small for rough tracks.

From testing both together I can tell you the VMX will be far more capable and faster on rough terrain. The small wheels on the M5 limit it to groomed surfaces. The bike is very stable for sure because it is so light and the gyro is very powerful. For the size of the VMX compared to the M5 you get a bike that is capable of 40mph off road. The long travel suspension on the VMX handles the bumps and jumps but the M5 has very simple suspension (unless upgraded) and lacks the dampening to control the bike well at speed. Plus it has short travel. The worst part is that the front tire hits the front of the chassis on a box stock bike so thats like hitting the front brake each time it bottoms out. If you flip the forks around you get better clearance but it is what it is.

Bottom line if you modified a M5 really well and fixed its design flaws and put a good driver on it the bike would give the VMX a hard time on certain tracks and the VMX would be better on other tracks. Each have their advantages.

I made some guide wires out of 1/8" music wire.They are the same lenght as stock and i soldered the tips with silver solder due to the fact that there is less surface area.I think they look a little less cumbersome and i hope they work.I may even solder a very small gusset on ends to help with the wear factor.I have been running my bike on pavement and have gone thru 2 sets of wires so far.I silver soldered my stock ones also just to build them back up wear they were ground down.




I tested my homemade guide wires again today.Before going out i added bigger globs of silver solder to the tips and they work great.If anyone plans on making a set you should use 1/8",/3.17mm music wire available at lhs.You MUST use a torch to make the V bend.Get it cherry red and slowly bend it over.The ends that go into the holder i narrowed down to 3mm dia. with a dremel drum sander.Don't forget to wrap the V-bend with small guage copper wire and then soak it with globs of solder and they will last a long long time.

Good news, customer service got back to me and they're going to ship out a new motor. I threw out the idea of getting it overnighted but I had to pay the extra if I wanted it overnight so I stuck with the standard shipping, will probably be here next week.

The only thing I noticed is they shipped me the 4200kv motor instead of the 4800kv motor. Less speed but cooler temps and I could gear it up slightly if I want to gain the speed back...

EDIT: It appears the 4800 is either out of stock or discontinued which explains the 4200. Can't wait any longer to get this going!!!

I changed the spec on the motor to 4200 to get the temps down and have better reliability. The very first bikes did have 4800kv motors. We dont see melt downs or failures very often at all luckily with the 4200's and the bike runs strong still. The difference between the two motors is not so drastic when you run them side by side and on the up side the 4200 gives better run times.

Motor Maintenance

Please check the motor front and rear cover screws after a few runs. The screws that hold them in place are small and there is a lot of vibration and stress.

Just the other day we were running really hard and jumping into the grass from the parking lot from our ramp which is about 7ft long and 3ft tall with a good curve to it. We launch bikes 35ft over to the grass which is lower than the parking lot so the drop is taller than us probably 10ft. So Paul comes screaming off the parking lot full speed and hits the jump but in flight we notice two objects sailing through the air. One is the bike and the other was the motor back plate!

The moral of the story.... check the screws on your motors.
