My son's 16.0 24v. has a lot of friction in the forward direction and even more friction in the other direction. The bike works well, but because of the extra friction the batteries are drained after half an hour. Has anyone opened the electric motor to replace the bearings ? Thanks.

I have some more questions regarding the 2001 ignition system. Is the sparkplug cable replacable ? It doesn't seem to want to move out of the coil. Is it possible to replace the copper cable with a ceramic cable ?

Thanks, I missed that.

Hi, I have a 2001 TXT 280 (not PRO). Does anyone know the ignition stator OHM values ? Thanks

I have seen Ernie's name and David's name here in the Forums a number of times. In 1992 I lived in Edinbourgh and had the honour of knowing and riding with both of them. Does anyone know how is Ernie doing these days ?

If the Big wheel 80 is the same size as a full size trials bike, then I should probably look for a Beta 80 Junior. This should be much smaller, should'nt it ?

Can anyone post a picture of a big wheel 80 standing besides a full size Trials bike ? I want to get an idea of the size of a 80 (never seen a 80 in person). My 9 year old son is getting too big for his OSET 16.0, but the 80 might be too big for him. Thanks.

I also think it has more to do with with suspension characteristics and rider technique than it is with power. I think the front fork is too stiff for his weight. He can't compress it with the bike static. Has anyone tried to open the Forks ? Two third of their length is empty, so I am wandering if they have any springs ?! Maybe elastomers ?

Has anyone gone from 24v to 36v ? My son is 8 and has been riding his 16.0 24v for more then 2 years. He rides well but finds it hard to lift the front wheel. Does the 36v. have much more torque making it easier to lift the front wheel ? Thanks.

Hi, I am looking for clutch friction plates and springs for a 1999 Easy 290. Does anyone know where can I buy these items ? I e-mailed Birkett, but got no answer,

I am assembling a 2006 GasGas Pro 280 which was imported in parts. I have a few questions concerning the electrical parts situated near the steering stem. There are two black wires coming out of the Thermostatic switch, to what are they connected ? The DC rectifier for the Fan has two yellow wires coming out of it, where are they connected ? Is the coil situated on the right side of the frame opposite the CDI ? I have checked in www.trialspartsusa.com/tech.html but they have different colored wires in their wiring diagrams. The bike has a Kokusan electric system. Thanks.

Here is a link to a magazine comparison between the WR250, T-ride and the Sy 250F. Anyone with good enough French to translate the article ? What interests me is whether the T-ride has the Sy 250F Cams, Carburator, Flywheel and gearing or is it closer to the WR engine wise ? http://www.scorpa.fr/uploads/revues/french...ovembre2007.pdf

Endurocross It is interesting that Trial bikes are doing so well in a speed race against Enduro and MX bikes. Maybe they are modifying their suspension to cope with the higher speed ? The T-ride seems ideal for this type of event...

Yep, a big difference. Hopefully in 2008 I'll upgrade by a decade to a 4-stroke Scorpa !

Wow ! Yesterday I rode a 4RT. There is a very big difference between it's suspension and the suspension on my old Scorpa Easy !!
