Suzuki TU250 G Grasstracker
Suzuki TU250 GB Grasstracker Bigboy
2002—
| I have tried to tell the Suzuki TU 250 Grasstracker model
history on this page, as I know it. The page is still under construction.
I would be grateful of any contributions — sales brochures, magazine ads,
magazine articles, pictures, specs, facts, corrections etc. Please scan the material
in JPEG format (large enough that all the details are visible) and send
them to me. Please tell me the source and the publication date if possible.
If you send me pictures of your own bike, please follow these
instructions. |
 
2002 Suzuki year code: K2
Suzuki launched two new models in Japan for the 2002-year's program
in March 2002, the TU250G Grasstracker and a larger version of
the same model, the TU250GB Grasstracker BigBoy. As the model
name TU250 reveals, the models have a lot in common with the street
sports model TU250 Volty, but the design and the chassis are more
suited for riding in the terrain. No, they are no offroad machines,
at least no more than the early seveties' TS machines were.
Mechanically the models are almost identical, except for some
details. The Bigboy model has a kick starter as well as an electric
starter and has got larger wheels and tyres. Both models use the
same frame and engine.
Even the design is more seventies than 21st century, personally
I like the looks of the bikes and wouldn't mind using one when
taking a spin to the beach or for shorter trips anywhere, they
are rather cheap models. In Japan, that is. Unfortunatelly the
models are not imported to Sweden. Probably the model is not sold
in any countries outside Japan.
Colors available (Grasstracker Bigboy): Yellow/Black, Blue/White,
Orange/Black.
Colors available (Grasstracker): Red/White, Silver.

2003 Suzuki year code: K3
In my opinion, the 2003-year's models are not as beautiful as
for the first model year. The differences are small, but noticable.
The graphics on the fuel tank are simpler, and that's about everything
that's changed for 2003.
For those who like the looks of the Suzuki's multi-purpose bikes
from the early seventies, the new looks of the Bigboy is perhaps
welcome. It the wheels were chromed, the similarity would be even
more striking.
Colors available (Grasstracker Bigboy): Yellow/Black, Blue/White,
Silver/Black.
Colors available (Grasstracker): Red, Silver.
