Our aluminum tube swing arm for tires for 180 up to 360. We can supply the swing arm for all chain driven bikes. According to the selected tire width, we manufacture the swing arm exclusively for your bike – the installation works plug & play. Nothing has to be changed on the vehicle itself: Original swing arm out, RFB-swing arm in – done. The integrated, tensionable pinion shaft compensates the chain offset due to the wide tire. The rear wheel is centered to the vehicle at the end (no offset). Because of the tube construction, the swing arm has great stability and is very light at the same time. We offer the swing arm with different surface options such as aluminum raw, high-gloss polished or black matte / glossy powdercoated. Measurements: We need the original rear swing arm, the rear wheel with brake system and sprocket carrier as well as the rear wheel axle with spacers. Simply send us the parts by mail to our address in Germany. We will then send the parts back to you. If we do not need some parts (because we have the measurements already), we will contact you shortly after your order. Information about the TÜV-entry in Germany: We deliver various documents like technical drawing, material specification, TÜV sample report of an identical vehicle (if available) for the TÜV-Einzelabnahme (individual acceptance). If there are problems with the TÜV-Einzelabnahme, we guarantee the TÜV-entry here at our workshop. Scope of delivery: Aluminum tube swing arm, ready for installation incl. wheel bearings (swing arm is approx. 25-50 mm longer than original swing arm because of integrated pinion shaft) pre-assembled pinion shaft and wheel stub axle with eccentric adjustment tensioners and swing arm bearings cover pinion shaft if double shock absorber is selected: upper frame spacers for shock absorber (Note: You need to measure the length of the frame spacers after the installation of the swing arm.

We widen the original cast wheels of your motorcycle! The advantage is that you can then drive wider or even changed in diameter wheels / tires without having to make further changes to the bike. The wheel hubs remain unchanged, only the rim beds are changed. Of course you have to take into account the clearance wheel-chain, wheel-cardan, wheel-belt and the width of the swingarm. In most cases, the original rim widening for motorcycles is also the most cost-efficient way to realize wheel size changes. For widening, the original rim beds are turned on special lathes and then machine-welded to corresponding larger rim beds using the TIG welding process. The weld is no longer visible in the outer area of the rim beds and the rim looks like a "normal" rim. A strength certificate with identification is enclosed. Note: If you are unsure whether your rim can be widened, send us a picture by mail in advance! We will be happy to advise you. Here's why: Cast rims, which have a rim bed, into which no cast spokes run from the inner star, can generally be widened (that's most rims). However, there are also rims where the cast spokes merge into the rim bed. Here, it is usually difficult or even impossible to widen the wheel. Furthermore, the following applies: A rim can be widened by a maximum of 2.0" in the same diameter, e.g. 3.5" x 17" to a maximum of 5.5" x 17". Wider is also possible, but then the diameter of the rim must be increased by 1", e.g. 5.5" x 17" to 10.0" x 18". The wheels are blasted before processing and must be resurfaced after widening, which we of course also offer - just select the desired variant (coated, painted, polished). Our variants here in the store are always based on delivered 17" or 18" wheels. Other dimensions on request by mail. Please send or deliver wheels without attachments (brake discs, tires, sprocket carrier) by mail to us. The procedure: Place your order here in the store or send us an e-mail request Send the bike to us by mail (print out the order confirmation and put it in the package) to the address RF-Biketech GmbH, Mühlweg 10, 97720 Nüdlingen, Germany We widen the wheel as desired and treat the surface depending on the variant We send the widened wheel back to you Scope of delivery: Widened wheel (wheel bearings are not mounted but attached in the package) technical report with identification (Festigkeitsgutachten) for TÜV (Germany)
