What Does The Future Hold?
Overall the Shiver has the makings for a great bike. It displays the craftsmanship that is typical to all Aprilias, but it still needs some further refinement to reach its full potential. This is a bike that can nearly do it all, but despite its attractive appearance and comfortable riding position, at this price one expects more from a motorcycle. Little things like the lack of a spring-loaded detent with the turn-indicator switch often left us paranoid as to whether or not the blinkers were on. The gauge cluster also left us annoyed with how complex a normally simple device was to operate. We could sense that the engine and chassis wanted to give us more in the canyons but were being held back. After pondering over the Shiver we started to wonder why Aprilia didn't just add on a worthy suspension and create a little brother to the Tuono. Our best guess is that this engine and chassis combo could be the basis to many other platforms that Aprilia will release in the future-a more sport oriented model with proper suspension being one of them. If that's the case then we can't wait to ride it. Until then the Shiver will be a great idea that just fell short.

The unassuming gauge cluster...

The unassuming gauge cluster is actually deceiving. The LCD panel can show a number of different menus depending on which hand you use to toggle.

The 750cc engine is Aprilia's...

The 750cc engine is Aprilia's first attempt at a proprietary engine, though there are remnants of Rotax in certain areas. Note also the laterally mounted rear shock.

Test Notes
+ Comfortable seating position
+ Strong middleweight engine
- Gauge cluster is anything but intuitive
- Suspension gets overwhelmed quickly
x Engine and chassis have much more potential.
