Popular Post DILLIGAD Posted May 22, 2019 Popular Post Share Posted May 22, 2019 Awesome bike the Aprilia .. Back in the day there used to be a dealership in Croydon that used to have them displayed outside on the pavement .. One in classic Aprilia paint scheme just needs a bit more green in it .. That’s where I bought my Guzzi v11 Le Mans, titanium exhaust&remapped ECU from.Nice people!Sent from my iPhone using Tapatalk 3 Link to comment Share on other sites More sharing options...

If rotary? Hmmm a bit dodgy for a bike? Still, with all those exposed chains maybe that is the least of the rider's worries.

Popular Post thaiguzzi Posted May 24, 2019 Popular Post Share Posted May 24, 2019 Yamaha Fanboy 1.0 Another neat XSR700 custom, this time French. One of my favourite currently available motorcycles. Yamaha fanboy 2.0 Just been reading and watching the first official journo ride 'n' reviews of the eagerly awaited new Tenere 700 or T7. IMHO prolly THE IDEAL bike for this country and at the top of my shopping list. No electronics, amply power and torque, lightweight compared to the opposition, and it says Yamaha on the tank. And Tenere.... 8 and a 1/2k GBP in the UK. Keep it around 375-400k TB here and i may have to buy one. This is 2019 m/c porn for me. 4 Link to comment Share on other sites More sharing options...

Justgrazing Posted May 24, 2019 Share Posted May 24, 2019 (edited) I ain't condoning this sort of thing but take a look as some in the Industry are saying this is part of the future of bikes .. Top bike has a 3D printed frame though still a mock up at this time .. Bottom one is also said to be 3D printed though that shape would be quite achievable in a conventional machine shop anyway .. The circular shape frame does make a lot of sense from an engineering point of view but is not easy to make aesthetically pleasing shall we say .. 5 axis millers and routers could theoretically make similar to the lattice one though i suspect would be quite time consuming ..

Que? 73 bhp 50 Ibs ft torque 204 kgs wet weight is overkill? I'll tell you what overkill is. a 1250cc 250 kg 125 bhp GS bus masquerading as a touring bike capable of a bit of off road. Not only is that overkill, it also contravenes the trades description act. 4 1 Link to comment Share on other sites More sharing options...
