PopularMechanics is well established magazine, and has an excellent website where there are two very good articles under the theme of kartbuilding:
- Doing 100 Mph (miles per hour) in a Rotax RM1/F1 Go-Kart
- One of Honda’s Newest ATVs (all terrain vehicles) from 2000
Doing 100mph in a Rotax Go-Kart
This article describes how a Rotax Go-Kart with a 34hp two-stroke engine of a mere 125cc! can achieve 100mph!! Including the driver, the total weight of the kart comes to only 300 pounds (or 136kg), with dual disc brakes on the rear axle, and disc brakes on each front wheels.
The Go-Kart has an amazing transmission. It has a 2 speed direct drivetrain which is chainless and shifts electronically via two large paddles mounted onto the steering wheel. There is an electric starter which can also move the kart in reverse!!
Overall its an excellent article with some very informative and detailed photos, and well worth a look. If you don’t have the $8000 money to buy it, you might at least get some good ideas! The article again is located at: http://www.popularmechanics.com/outdoors/adventures/1278136.html
Details, Specs and Trial of a Honda ATV (Foreman Rubicon 400)
Although this article was written in 2000, it contains some up-to-date details and information on the transmission and capability of an ATV (All Terrain Vehicle). Details on the “Hondamatic” transmission providing engine braking are included, along with Limited Slip Differential are included! This article is definitely for the off-road enthusiast.
There are no exact details on the engine specs or the costs. There is also a hayes owners workshop manual available for this ATV. Perhaps some of the technology could be taken off one of these ATVs and transplanted into a Off-Road Kart.
