Suzuki DR-Z4 Derivative Model (1) "Super eager for the revival of the single sport "Goose"! Suzuki DR-Z4 Derivative Model (1) "Super eager for the revival of the single sport "Goose"!

The resurrected Suzuki DR-Z4S/SM, the heart of which retains the basic design while almost completely redesigning the internal parts and equipping it with FI, electronic throttle control, and the latest fuel delivery system. With an engine this good... why not expand it beyond the DR-Z? Mr. Suzuki!*The CG in this article is the imagination of the editorial staff. It has nothing to do with Suzuki, so please refrain from contacting dealers.

Is engine lateral development Suzuki's royal road?

The Suzuki DR-Z4S/SM is back after a 16-year absence, following the end of sales in Japan in 2009. The engine retains the basic design, but is almost entirely newly designed to meet the latest emission regulations, and the chassis is completely brand new. The DR-Z is the off-road GSX-R! The development team's commitment to the project is also refreshing.And when you ride it, you will find that it is, as you would expect, a very good machine. The most outstanding feature of the GSX-R is its engine, a 38 hp liquid-cooled single-cylinder that is both powerful and smooth, with excellent extension all the way to high rpm, and a gentle, easy response when the throttle is opened. It is not only fast, but also easy to handle.It would be a shame to have such a good engine monopolized only by the DR-Z! Suzuki, the "demon of horizontal engine development," has developed four models of the former GSX-R1000 (K5/6) 1000cc four-cylinder series and six models of the 800cc para-twin series, so it is only natural that we should expect to see a derivative model of the DR-Z4 series as well.

While retaining the basic design of the previous DR-Z400 series, the 398cc single-cylinder has been almost completely revamped. Fuel supply has also evolved significantly from a carburetor to an electronically controlled throttle FI.

Is there a chance for a premium single-cylinder sports car?

But the story doesn't seem so simple. According to the development team, the DR-Z4's engine is designed for off-road use, as typified by its dry sump, so it would be quite a challenge to develop it into an on-road model. 1,199,000yen, a rather high price for a 400cc single-cylinder vehicle, is also due to this difficulty in horizontal development (i.e., difficulty in reducing costs by developing other models). The price of 1,199,000 yen, which is quite high for a 400cc single-cylinder car, seems to be affected by this difficulty in horizontal development (i.e., difficulty in reducing costs by developing other models).If this is the case, even if a derivative model were to exist, it would have to be something very similar to the DR-Z4's configuration (an off-road tourer model?). If it is an on-road model, the unsuitable parts would have to be significantly modified. In any case, it will be difficult to drastically lower the price, and the DR-Z4 derivative model is likely to be a highly premium model that people will buy even if it costs that much more.If this is the case, the first candidate would be the Goose, Suzuki's excellent single-cylinder sports car. If it is made into a premium and maniacal single-cylinder supersport, it will surely have its supporters.In fact, we at Webike Plus would be the first to want one! So, we went ahead and created a CG of our fantasy. How about we call it "Goose 4S"? (continued)

[Goose 4S, IMAGE CG] The Goose is eagerly awaited for a revival as a single supersport equipped with the DR-Z4S/SM's liquid-cooled single-cylinder! As a single-cylinder café racer with a neoclassical feel, will it be a good rival to the Husqvarna Vittpillen 401?

The Goose 350, introduced in 1991, was powered by a high-revving oil-cooled single-cylinder engine (33 hp) with a red zone of 10,000 rpm, mounted on a tubular steel diamond frame; a 250cc version followed in 1992.

I think this kind of derivative development would be super nice...what do you think?
