Splice Supermoto by Rotobox Is Carbon Fiber Tasty...And $34,000

Slovenian house Rotobox is known better for its carbon fiber wheels (if you’ve never seen a pair, they are very, very nice), but now it seems that Rotobox is looking to sell you more than just some round bling.

Starting the Rotobox Moto brand, the company has released its first project: the Splice supermoto.

Based off the Yamaha WR250 and WR450 platforms, Rotobox has cranked things up to 11 for these street-shredding machines, with some help from the good folks at the Yamaha Austria Racing Team (YART).

The machines aren’t cheap, however. Pricing is set at €29,830 not including VAT.

For that coin though, you do get quite the supermoto street bike. The Rotobox Splice comes with a set of carbon fiber wheels, naturally, and they carry a Brembo T-Drive 320mm disc with a Brembo GP4RR caliper.

Suspension is by Öhlins, with FG461 forks at the front, and a TTX Flow shock at the rear – both units lowered from MX spec for supermoto duty. A special triple clamp holds the forks, with a 14mm offset.

If you look at the rear of the machine, you will see a peculiar sight, as a Yamaha YZF-R6 swingarm has been grafted to the WR450F frame. This allows for a 5.5″ rear wheel with a 190mm width Bridgestone slick – which is a bit overkill in our opinion, but certainly interesting.

The bodywork has been overhauled, with the highlights being the 3D-printed front fender and rear mudguard. A custom exhaust has also been added, though it is hard to spot thanks to its black ceramic coating.

Final touches include a slipper clutch, ceramic coated engine covers, a unique livery, and a custom seat. The Rotobox Splice weighs just 262 lbs when it is fully fueled, which isn’t too bad for a street bike. That $34,000 price tag though…
