For Vespa GTV-300 and GTS-300 Sport

This is a summary of specs and products that may be useful to some and I list them here so that I can always access it in a store with my Windows Phone.

The Color Red is what I decided to use because of local availability.

Tires:

Front: 120/70-12 51p (Michelin Power Pure SC)

Back: 130/70-12 MC 59-P (Michelin Power Pure SC)

Molossi Belts: belt_list_2015_7

Engine Oil (1.1 – 1.3 Liters)

SAE 5W40 Synthetic Oil that meets API SL, ACEA A3, JASO MA

Brands Recommended:

• AGIP Grip City Hi-Tec 4T SAE 5W40 (Piaggio Recommended)
• Motul 4W40 300V Factory Line 4T Synthetic (Recommended Highly)
• Motorex 5W40 Synthetic Power Synt 4T (Recommended Highly)
• IPONE Scoot 4 10W40 Synthesis

Hub (GEAR) Oil (250 CC)

SAE 80W90 that Exceeds API GL3

Note: Gear Oil may be confusing. The 80 or 75 in the SAE refers to oil that is specifically made for gears such as 80W90 or 75W90. However, an oil with 75W90 has about the same viscosity as a 10W40 Oil. Some manufacturers such as Motul make a premium oil that is excellent for the gears but they label it a SAE 10W40. When the label has a 75 or 80, it generally means that there are specific additives in the oil that may not be good for an engine.

Brands Recommended:

• AGIP GEAR 80W90 (Piaggio Recommended)
• Motul TRANSOIL EXPERT 10W40 (Highly Recommended)
• Motul Scooter Gear 80W90
• Motorex Scooter Gear Oil ZX 80W90

Coolant (2.1 Liters)

50% Deionized Water and 50% Ethylene-Glycol with Added Corrosion Resistance (Mono-ethylene Glycol Based) Meets CUNA 956-16

• AGIP Permanent Plus Coolant (Piaggio Recommended)
• Motul Motocool Expert (Recomended)
• Motul Motocool Factory Line (Highly Recommended)

Transmission Cable Lubrication

Use the Same Oil as for the Engine- 5W40 Synthetic (See Above)

Brake Lever Grease

White Calcium Complex Soap-Based Spray Grease that meets NLGI 2; ISO L-XBC1B2

 

Exhaust Compression Gasket Seal

A less expensive compression gasket can be purchased at a local Yamaha Dealer instead of a Piaggio Dealer. The Yamaha Part Number is 3YF-14714-00 and in Canada it is half the price.

Brake Caliper Banjo Washer

These are recommended to be replaced when you remove the brake hose but are difficult to find since they normally are shipped with a new caliper. However, you can get them at a Honda or Yamaha Dealer using these part numbers: Yamaha 90430-10005-00 or Honda 90545-300-000

 

Descriptions of Standards:

 

JASO

In 1993 the new JASO FA, FB and FC specifications (in order of increasing severity) came into force for 2-stroke engine oils, followed later by JASO FD. JASO is the acronym of the Japanese Automotive Standardizing Organization. The specifications are based on tests carried out on the Honda DIO AF27 engine (lubricity, torque, detergence) and the Suzuki SX800R (exhaust smoke, exhaust ports clogging). The JASO system includes a logo that can be printed on packaging by lubricant producers. To do this, the producer must apply to JASO to be registered, with an official declaration attesting that the product conforms to the required performance levels. Following the success of the 2-stroke specifications, JASO then implemented a similar system for 4-stroke oils. This system has two specifications, MA and MB. Both require the same engine performance (API and/or ACEA levels). The difference between the two specifications is in their antifriction, which can
affect the correct operation of wet clutches.

ISO

The JASO specifications were later integrated with the “global” specifications issued by the ISO: in increasing order of severity, these are GB, GC and GD. The ISO (International Standardizing Organization) intended these specifications to form a set of global standards, i.e. specifications that would meet the technical requirements of all builders of 2-stroke engines worldwide. The most common of the ISO specifications is ISO-L-EGD. This specification covers the same requirements as JASO FC (lubricity, torque, detergence, exhaust smoke, and exhaust ports clogging). While an exact comparison between the JASO FC and ISO-L-EGD levels of severity is not strictly speaking possible, due to differences in the testing methods, ISO-L-EGD can be considered as representing a higher level of severity. Unlike JASO, the ISO system does not have official logos and/or a formal system of official registration or approval.

SAE viscosity classification

The SAE (Society of Automotive Engineers) has issued two classification systems for lubricants based on viscosity, one for engine oils and one for transmission oils. Both systems classify lubricants based on viscosity at low temperature (the classification prefixed with the letter W for Winter) and at high temperature (100 degrees C). “Multigrade” lubricants are lubricants that can be classified according to intervals at both low and high temperatures, and they provide constant viscometric performance (cold starts and protection at high temperature) in a very wide ambient temperature interval. The SAE viscosity classification is not applicable to “self-mixing” 2-stroke oils containing diluting agent.

API classifications

API is the acronym for the American Petroleum Institute. For motorcycles, the API service classifications of nterest are:

1. Engine oil (4-stroke). The API Engine Service Classification is divided into S-series (S as in Service station) for use in petrol engines, andC-series (commercial) for use in commercial and industrial vehicles (with diesel motors).
2. Transmission oils. The series of performance levels is marked GL (for Gear Lubricant) followed by a progressively higher figure indicating the higher level of severity. Essentially, API GL-3 oils are anti-wear, while GL-4 oils and, more generally, GL-5 oils have superior extreme pressure (EP) properties.
3. 2-stroke oils. This series of API classifications is marked with a progressive letter, from A to C, according to the increasing level ofseverity. For many years these API classifications were the reference standard. From the 1990s onward, however, due in part to the factthat the API standards were not revised, they were progressively replaced in terms of importance by JASO and, eventually, by the new ISO

standards.

ACEA

European engines, traffic conditions and speed limits are different from those in America. Consequently, although the API sequences were available, the associations of European carbuilders (formerly the CCMC, Comité des Constructeurs du Marché Commun, which evolved into the ACEA, Association des Constructeurs Europeens d’Automobiles) developed a series of “sequences” based on tests conducted mainly on European engines. These performance specifications are intended to define the minimum performance requirements. Some builders take the ACEA sequences and add further, original specifications of their own. The ACEA sequences are divided into three classes according to use:

• gasoline engines (A)
• diesel engines for cars and light duty commercial vehicles (B)
• diesel engines for heavy duty commercial vehicles (E)

DOT

This acronym (Department of Transportation) is commonly associated with a set of specifications that are applied to brake fluids. The specified levels are DOT3, DOT4 and DOT5. The requirements of DOT4 in particular are more severe than DOT3, with regard to boiling point (dry and wet), but the same cannot be said of DOT5 with regard to DOT4.

NLGI

NLGI is the National Lubricating Grease Institute. The most common NLGI classification is the one that defines the “consistency” of a grease. The NLGI mark is followed by an increasing figure indicating the “hardness” of the grease. A “better” consistency does not exist as such. This depends on the mechanical parts involved. Also, the consistency grade is not an indication of any other properties that may be required from or possessed by a grease (adhesion, dripping temperature etc).
