The 2008 Gilera GP 800 pairs an 839.3 cc V-twin with an automatic CVT and a chain final drive. Its technical sheet lists 75 ch and 76.4 Nm; the available manual copy specifies NGK CR7EKB spark plugs. Confirm the bike’s exact version and consult its manual or model-year parts diagram before ordering components.
What are the specifications of a 2008 Gilera GP 800?
Moto-Net labels its figures as manufacturer data. Its technical sheet describes a liquid-cooled, 90-degree, four-stroke V-twin with electronic injection. The manual listing rounds the engine displacement differently, so the figures below retain each source’s wording.
| Specification | Published detail |
|---|---|
| Engine and cooling | 90-degree, four-stroke V-twin; liquid cooled (Moto-Net technical sheet; manual listing: Gilera GP 800 manual copy) |
| Displacement | 839.3 cc (Moto-Net technical sheet); 839 cm³ (manual listing) |
| Bore × stroke | 88 × 69 mm (both listings) |
| Compression ratio | 10.5:1 (Moto-Net technical sheet); 10.5 ± 0.5:1 (manual listing) |
| Fuel system | Electronic injection (Moto-Net technical sheet) |
| Maximum power | 75 ch at 7,250 rpm (Moto-Net technical sheet; manufacturer data, not an independent test) |
| Maximum torque | 76.4 Nm at 5,750 rpm (Moto-Net technical sheet; manufacturer data) |
| Transmission | Automatic CVT with torque converter and centrifugal clutch; belt primary drive and chain secondary drive (Moto-Net technical sheet) |
| Exhaust | Closed-loop system with lambda sensor and three-way catalytic converter (Moto-Net technical sheet) |
The belt is part of the primary transmission, but the secondary drive is a chain. That distinction matters when identifying service parts: the GP 800 should not be treated as a conventional scooter with a belt final drive.
Which spark plugs does the Gilera GP 800 use?
The available manual copy specifies NGK CR7EKB and describes the engine as having double spark plugs. Check the manual for your exact vehicle and establish the required quantity before buying; do not infer the number needed from a listing for a single plug. The manual copy is hosted by a third party, so confirm the specification against the correct manual and the bike’s version.

Where can you find parts for a 2008 Gilera GP 800?
Start with a model-year parts diagram rather than relying on a broad model-name search. The 2008 Gilera GP 800 parts catalog organizes drawings by motor, frame and electrical components, and includes the air filter number 852944 as well as transmission-chain-related parts. A separate genuine-spares catalog provides component drawings and part-number lookup.
- Choose the 2008 GP 800 diagram. Navigate to the matching year and model, then open the relevant system drawing.
- Identify the component and diagram position. Compare its shape and position with the part fitted to the bike.
- Check the OEM number. For example, the catalog lists air filter 852944; use that as a lookup aid, not as proof of universal fitment.
- Confirm fitment with the seller or a qualified parts supplier. Provide the model year, version or market details where available, and ask the supplier to verify the part against the diagram and vehicle identification.
A 2025 Polini engine-parts catalog also lists a Gilera GP 800 4T liquid-cooled application with 2008 coverage. That is evidence of a catalog application, not confirmation that a specific item is in stock or fits every 2008 machine. Catalog entries do not establish current price, availability or interchangeability.

What tire size is listed, and what should you verify?
The available manual excerpt gives a front tire size of 120/70-16. It does not establish a complete, version-specific front-and-rear tire set. Check the tire sidewalls and the correct vehicle manual before replacing either tire; do not use the front-size excerpt to select the rear.
