Searchability:
If a well-scanned PDF, it may be text-searchable by part description or number. Crucial for efficient parts lookup.
Quality:
Dependent on the source. If digital, quality of scans/digital rendering is key. If printed, paper and print clarity are factors.
Binding:
If printed: Spiral-bound, saddle-stitched, or perfect bound are common for workshop manuals.
Paper:
If printed: Durable paper stock suitable for workshop environments is preferred (e.g., gloss or semi-gloss coated paper).
Coverage Scope:
Comprehensive parts listing covering all assemblies and individual components of the 1988 Beta TR34 R 260. This is a catalog, not a repair guide, but is foundational for repair.
Engine Type:
Two-stroke, single-cylinder.
Displacement:
260cc (implied by model name '260'). Exact bore and stroke would be detailed in a full service manual, but this parts list focuses on component identification.
Bore X Stroke:
Specific bore and stroke figures would be detailed in a full service manual, but are integral to the 260cc displacement. For example, a bore of approximately 70mm and stroke of around 69mm could yield 260cc.
Horsepower:
Not specified in parts list context, but typically in the 20-30 HP range for this class.
Torque:
Not specified in parts list context.
Carburetor:
Likely a single carburetor, make/model (e.g., Dell'Orto, Mikuni) would be specified in the parts list. Common sizes around 26-30mm.
Reed Valve System:
Two-stroke engines of this era typically use reed valve induction. The parts list will include reed blocks, reeds, and associated fasteners.
Cooling Method:
Air-cooled.
Ignition Type:
Contact breaker points or electronic CDI ignition typical for the era.
Typical Intervals:
While this is a parts list, common service items would include piston ring checks/replacement (e.g., every 20-30 hours of riding), gearbox oil changes (e.g., every 10-15 hours), clutch adjustments, and spark plug replacement. The manual helps source these parts.
Air Filter Cleaning:
Air filter cleaning and oiling is a frequent maintenance task, parts for the air filter housing and securing clips are included.
Engine Oil:
Would typically require a high-quality 2-stroke premix oil. Specific mix ratio (e.g., 50:1, 40:1) and oil type (e.g., synthetic, mineral) would be in a service manual, but the oil filter and seals are in the parts list.
Gearbox Oil:
Typically a dedicated 2-stroke gearbox oil (e.g., SAE 75W/80 or 10W/30). Capacity and specific API rating would be in a service manual. Gaskets and seals for the gearbox are in the parts list.
Brake Fluid:
DOT 3 or DOT 4 hydraulic fluid for the disc brakes. Parts list covers master cylinder seals, caliper seals, and brake lines.
Common Wear Items:
Piston and rings, clutch plates, wheel bearings, suspension seals and bushings, carburetor jets, and spark plug are common wear items for this type of motorcycle. The parts list is essential for replacing these.
Beta Motor History:
Beta Motor S.r.l. is an Italian manufacturer founded in 1904, originally known for bicycles, and later specializing in motorcycles, particularly off-road and trials bikes.
Tr Series Evolution:
The TR series represented Beta's dedicated line of trials motorcycles, evolving through various engine sizes and chassis refinements to meet competitive demands.
Tr34 Generation:
The TR34 was a significant iteration in Beta's trials lineup, reflecting advancements in frame geometry, suspension, and engine tuning for improved performance in competitive trials events.
Production Period:
The 1988 model falls within the late 1980s period for Beta's TR lineup.
