I don't even think GG has a dealer in the US and they are probably the biggest off-road bike seller in the world.
I think the only way GG will be able to claw back some small percentage of the world market they will need to supply bikes to there dealers on consignment
They have numerous dealers in the US and Canada. When you bring out a bike as good as the current offering memories of financial instability are quickly forgotten - just about everything that that the US market has been asking of GG has been addressed with the new bike from standardizing the bolts and nuts, captive nuts where possible, weight and using mainstream suspension are making it very popular in the US.
In europe they have a good team with some of the former GG riders like Nambotin and McCanney back and managed by Giovanni Sala, there is David Knight riding the extreme events in the UK and they also have the TPI ambassador, Lars Enockle, riding the hard enduros (i think he and DK are riding the WESS events as well)
So now is probably the (most) right time to be reintroducing them in SA, but not if you are looking for quick financial gain (I think this applies to any brand in the current economy). I think in 2010 when i bought my bike GG SA were selling about 100 bikes a year so probably similar to Beta or Sherco
What i have noticed in the rest of the world is that bike shops are dealers for more than one brand of bike, not sure why that doesn't happen in SA?
