Motorcycle Cylinder Boring Machine
The motorcycle cylinder boring machines in the Sorveteira line are built for precise machining of the internal bore of motorcycle cylinders. The category includes two models with different diameter ranges — one suited for smaller-displacement engines and one for larger motors —, both featuring controlled feed per tool revolution, automatic depth trip and a dedicated fixture table for motorcycle cylinders. Designed for engine rebuilding shops and specialized workshops that need repeatable cylinder boring results. Check the individual model spec sheet to confirm the bore diameter and depth that match your application.
Specifications subject to change without notice. Some capacities listed may require optional accessories depending on the model. Refer to each unit's technical datasheet for exact dimensions and limitations.
Frequently asked questions
What does a motorcycle cylinder boring machine do?
A motorcycle cylinder boring machine machines the internal diameter of a cylinder to restore its original geometry after wear or to open the bore for an oversized piston during an engine rebuild. The process ensures roundness, cylindricity and the correct surface finish so the piston and rings seat and operate properly. It is a core operation in engine rebuilding shops that service motorcycles.
What is the difference between the BVC-65 and the BVC-90VE?
The BVC-65 handles cylinders starting at Ø 39 mm (approx. 1.54 in) with a standard boring depth of 160 mm (6.3 in) at 600 rpm, suited for smaller-displacement motorcycles. The BVC-90VE starts at Ø 47 mm (approx. 1.85 in) with a standard depth of 300 mm (11.8 in) at 420 rpm, covering larger engines. The right choice depends on the bore diameter and depth required for the cylinder you are machining.
What are the typical specifications of these machines?
Both models run on a 0.5 hp electric motor with belt drive, 220 V / 60 Hz / 3-phase power supply and a feed rate of 50 mm/min (approx. 2 in/min). Feed per revolution is 0.09 mm (BVC-65) and 0.08 mm (BVC-90VE). Both include automatic depth trip and a dedicated fixture table for motorcycle cylinders. Check each model's spec sheet for exact dimensions and weights.
What type of motorcycle is this cylinder boring machine designed for?
The machines are suited for motorcycle cylinders in general — street bikes, sport bikes, trail bikes and single- or twin-cylinder engines of small to medium displacement. Bore diameter range and maximum boring depth vary by model, so verify the specific model that matches the cylinder you need to bore before selecting your equipment.
How do I request a quote or technical support for the cylinder boring machines?
Contact Chinelatto through the quote request form on each model's page (BVC-65 or BVC-90VE) or directly via the commercial channel. For technical support, spare parts and after-sales assistance, visit the contact page or reach out to your regional representative.
