Project case study: GP45 Aprilia road bike

There's been much discussion online that our GP45 kit would make a stunning road bike. One creative customer requested us to build just that from a 2008 Aprilia SXV450. We made several bespoke parts, sourced some unusual extras and made it all functional for the road. The result has created quite a stir as you'll see on our news and reviews page.
