Frequently Asked Questions:
Do Derbi Senda parts fit the Gilera SMT?
All Derbi Senda parts fit the Euro 4 models.
How can a Gilera SMT Euro 4 be derestricted?
Gilera models with the Derbi Euro 4 engine have restrictions in the exhaust and CDI. At a minimum, derestriction requires replacing the CDI with an unrestricted version without a rev limiter, replacing the exhaust header with an unrestricted version and fitting a larger main jet. A complete package is available in our shop.
What speed does the Gilera SMT reach in stock form or after modification?
In stock form, it reaches a maximum of 45 km/h. After derestriction, the speed depends on several factors. Depending on the parts and final drive gearing used, a properly tuned setup can reach 75 to 95 km/h.
Does the carburetor need replacing when changing the CDI?
After installing an unrestricted CDI suitable for the model, only the main jet needs replacing, not the entire carburetor. After full derestriction, a size 90 main jet is recommended.
How many teeth do the stock front and rear sprockets have?
Depending on the version, the stock chain and sprocket gearing is 11 x 51 or 11 x 53.
Can the SMT be lowered?
Yes, just like the Derbi Senda. Lowering kits are available that lower the shock absorber mounting point.
When do the piston and piston rings need replacing?
For a stock engine, piston replacement is recommended every 10,000 km. For a derestricted engine or a cast iron sport cylinder, we recommend replacement after 7,000 to 8,000 km. A tuned engine with a racing cylinder kit requires even shorter maintenance intervals.
How often do the engine, chain and brakes need servicing?
For trouble-free operation, a gear oil change is recommended at least every 2,500 km, especially for derestricted or tuned engines. Racing engines require shorter intervals.
The chain should be cleaned and lubricated regularly, especially after riding in the rain or in difficult conditions. These checks should also include the condition of the front and rear sprockets and the chain tension. If the teeth are worn, meaning thin, bent or even broken off, the entire chain and sprocket kit needs replacing.
The brake fluid should be changed every two years, or more frequently with sporty riding. The condition of the brake pads also needs regular checking. If the friction material is too thin, the pads need replacing. The minimum thickness is marked on the brake discs. When replacing the brake pads, the disc thickness must be checked to ensure it still meets this limit.
