Market Background and Product Summary

With its release on the European market in the autumn of 2000, the TMAX brought a fresh wave of innovation to the European motorcycle market with its combination of “fun motorcycle-like ride” and “comfort as a commuter” thanks to sports bike type handling stability and impressive styling. Today, the TMAX is ridden and loved by a wide age group of users who praise its “high-speed stability and plenty of passing power” and its “handling of a sports bike that you can enjoy in anything from around-town riding to touring on winding secondary roads.” While maintaining the same basic model concept of the original TMAX, the new 2004 model features new technologies that (1) boost basic performance, (2) improve handling stability, (3) improve convenience and (4) refine exterior quality. The result is a more mature model with true TMAX individuality that offers a high-level marriage of boosted performance, handling stability, riding comfort, convenience and environmental friendliness.

Main Changes and Features

Boosted basic performance with adoption of fuel injection, etc.

In order to bring out even higher levels of performance and environment-friendliness, this new model adopts a fuel injection system featuring an especially fine atomizing injector. This fuel injection system is characterized by (1) return-less type fuel line layout, (2) idling stoichiometric control that enables lean running even in idle (removal of air induction system), (3) elimination of the cam sensor, (4) elimination of the air pressure sensor and (5) adoption of a compact 26-pin ECU. What’s more, an optimized system design has enabled a significant reduction in size. The result is a system that provides excellent response.
Furthermore, in order to achieve the ideal balance with the new fuel injection system, the specs of the pistons and connecting rods have been changed and the compression ratio altered from the existing 10.1: 1 to 10.9: 1. To accommodate the engine’s boosted performance, the V-belt spec has also been changed to ensure greater reliability. The combined effect of these improvements is even sportier running performance characterized by improved high-speed performance and better low- to mid-speed power development.
With the new fuel injection system and new muffler with catalytic converter, this new 2004 model achieves environment-friendly performance that clears EU-2 emissions standards.

Features like radial tires front and rear improve handling stability

To accommodate the boosted engine performance, the inner tubes of the front fork have been increased in size from 38mm diameter to 41mm. This further brings out the performance potential of the sport-bike-type telescopic front fork that is one of the defining features of the TMAX. What's more, a new double-disc front brake is adopted for even more stopping power.
Radial tires have also been adopted for front and rear. The front retains the existing size of 120/70R-14 while the rear tire size is increased from 150/70-14 to 160/60R-15 for another improvement in handling stability.

Other convenient features

Other features include (1) a theft-prevention immobilizer, (2) a parking brake (built into rear caliper assembly), (3) a new-design inner panel and (4) a new double-seat shape and cover material.
