Wide-Ratio Gearbox-KTM 690 Enduro/SMC & CCM GP450(BMW G450X)-Rally-Raid Products Ltd
Rally Raid Products: Wide-Ratio gearbox upgrades for KTM 690 Enduro and CCM GP450 (BMW G450X).
Over the years we have received a number of requests as to the feasibility of manufacturing an proper wide-ratio gear-set for the KTM 690 Enduro - something we agree would certainly enhance its overall ability as a genuine all-rounder and overland adventure bike.
Since the relatively close-ratio standard 690 gearbox was designed for primarily competition use, traditionally trail and adventure riders have had to compromise with either a lower cruising speed in an effort to retain proper low gears for serious off-road use; or otherwise raise the overall gearing for more comfortable/lower revving highway cruising, at the expense of the desired lower gears for off-road work.
While we pride ourselves on typically innovating new engineering solutions in-house, we are happy to concede that on occasion there are already established specialist engineering firms who have direct experience in a particular field.
In this regard, Rally Raid Products have partnered with fellow British engineering company Nova Racing (who specialise in road and off-road racing gearboxes) who have been able to develop the products our customers desire; and are delighted to announce that Rally Raid Products are now the official retail distributor for both their KTM 690 Enduro wide-ratio gearbox, together with a specific replacement gear-set for the recently released CCM GP450 Adventure motorcycle - that uses the BMW G450X enduro bike engine, complete with the original close-ratio 5-speed gearbox.
The table/s below give you an illustration of what can be expected from the upgrade. Essentially the overall gear-spread of 65.2% in the stock KTM 690 gearbox is increased significantly to 72.9% - effectively giving you much higher cruising speeds/cruising at lower revs while retaining the same low gears off-road, or conversely much more serious lower gears while retaining the original top gear cruising speed/revs - or indeed, a combination of the two - depending on you chosen final drive (chain and sprockets) combination.

Similarly, one potential criticism of the brand new GP450 lightweight overland adventure bike from CCM is that it retains the original (racing) close-ratio gearbox from the BMW G450X enduro. The NR/RRP wide ratio upgrade also extends the overall gear spread from a modest 64.3% to 72.7% - again, dramatically expanding the useful spread of gears, allowing you to retain low gearing for off-road work, while also reducing the revs at higher cruising speeds.

Prices and fitting options.
The KTM 690 Enduro wide-ratio gear-set comes fully assembled on new input/output shafts completely ready to fit into your original engine.
Because of the design of the G450X gearbox, the new wide-ratio gear-set is suppled as individual [loose] gears, and will need to be assembled on the existing shafts with the corresponding OEM circlips/washers/bushes - although this does offer purchasers a useful cost saving in return.
The retail price of the KTM 690 wide-ratio gear-set is £2200.00 GBP, while the GP450/G450X wide-ratio gear-set is £1300.00.
Should you wish to have either gear-set professionally installed, our UK service agents Torque Racing Services can fit either gear-set (including dismantling and rebuilding your engine with a new full set of gaskets) - for a fixed price of £450.00 to a supplied/bare engine, or £750.00 for a complete ride-in/ride-out service.
All prices are plus VAT(if within EU) and shipping, via UPS worldwide.

Once again, Rally Raid is listening to what people want and are working to provide it. Thank you RRP for doing what the manufacturers won't.
