Harley Davidson Sportster Thunderstreak

Photos Flyer

We decided to work on a Harley-Davidson Sportster XL 883R, to be presented, in preview, at the Motor Bike Expo 2016 in Verona. We think to improve his sportive look and his dynamic characteristics.

And here our list of code that we mount on this bike:

049907: This unit that uses generation 3 Dobeck TFI technology and has several advantages over previous models. With this fuel injection unit mixture adjustment is by means of 3 push buttons on the top face of the controller. Supplied with new simplified instructions. Part for Harley Davidson Sportster 883-1200 07-13 and XR1200.

403910: Adjustable and articulated, brake & clutch levers made entirely in Italy by Bolcato racing with high quality alloy. Micrometer precise screw to adjust lever distance. Pivoted levers that fold away upwards, to reduce chance of breakage in case of crash. Simply pushes back into place.

201206: This kit considerably improves original fork, which has an almost absent hydraulic, into a well controlled, progressive and stable unit. New valve kit, increases front stability, braking characteristics by consenting a perfect control of deceleration even under the hardest braking, it increases the grip entering and exiting a curve thanks to the immediate hydraulic control. You can use original springs and oil.

201213: Suspension riser kit is developed to raise the rear suspension by 58 mm on 04 onwards Harley Davidson Sportster models. Gives more sporty stance and reduces front fork trail for faster steering.

201904: This kit for Harley Davidson Sportster & XR1200 was created to purely aesthetic, can replace the unsightly factory bolts.

202302: This kit for Harley Davidson Sportster, made in lightweight CNC machined billet aluminium, replaces top and bottom triple clamps and it measure 8 inch wide. The increased size of the plates gives more rigidity and control. Kit ready for replacement, including shaft, wheel spacers support for the original lighthouse and dashboard. Spare parts available for this kit.

202607: New and innovative these “bolt on” riser allow the use of 1” handlebars with the standard 3.5" bolt center, without the need to replace original top trees. Using the original bolts and DAMPERS.

203709: Kit with 4 pistons Brembo calipers (Gold) and mounting bracket (Available black anodized) for Harley Davidson Springer. Works with OEM master cylinder, brake line and rotor. The kit includes the brake pads. Increases braking power and modulation.

204015: Performance air filter designed for the Harley Davidson XL883 / XL1200 models. The 65 mm diameter tubular stainless steel elbow is produced by a unique patented process that allows the use of thin walled lightweight (only 305 gr) construction. The kit includes a well proven Sprint Filter (Water repellent) ‘Cone’ air filter, black finished tubular elbow manifold, crankcase breather pipes and required fittings. For this kit spare parts are available.

205708: Harley Davidson Sportster 2014 up 300 mm rear Floating brake rotors kit. The kit contains:
- black anodized billet aluminum bracket
- Fully floating front brake rotor, with high-quality band, “Fully Tempered” made by New Fren.
- Compatible with ABS.
It use the OEM master cylinder, brake line and caliper.
Increases braking power and modulation.

206910: Multi adjstable billet aluminium CNC machined rearset footrest kit specifically designed to fit the Harley Davidson Sportster (2004 on). Superbly manufactured and available in either black or silver anodised finish. This feature adjustable footrest position via eccentric footpeg mount. Gear linkage gives more precise shifting. Includes nre brake fluid reservoir and Brembo master cylinder. No more scraping around corners with these fitted!

207600: This light weight pulley replaces stock, made of aluminium billet drive pulley temperate and surface hardened. Special steel galvanised inner part changeable totally stainless, reduced weight at 680 gr. This 29 teeth pulley can be used to increase speed on Harley Davidson XL Sportster 883 2004-2013 and XR1200. Using the original belt.

207665: The Tensioner is developed primarily to dampen the belt tensions in deceleration and stress to the wheel bearings and the pinion, maintaining a constant pressure. This particular model is obligatory where you want to lift up the rear, because the increased inclination of the swingarm, generates (inevitably) a difference in dimensional between the belt drive and swingarm extension, only compensated with a bending of the lower branch to belt drive that balances during the excursion of the swingarm. The aim is to extend the life of the belt and the wheel bearings and gearbox, as well as facilitating the smoothness of the secondary transmission and reducing the excessive tension. Maintenance free belt tensioner. For reasons of space it is necessary to modify the exhaust system and the rear brake master cylinder position.

208506: This new engine protector crash pad has been designed to dissipate/disperse the power of a collision over a wider area and to more points, so avoiding stress at one point (This product has been tested during racing!). Supplied with fitting hardware and available in black, silver or red anodised finish. Part for Harley Davidson XL Sportster. Spare parts are available if required.

208846: Supplied in unpainted fibreglass ready to finish, Ideal for those who want a (Dirt Track) look. This is not a “bolt in” kit as it is necessary self constructed brackets to install it.

208850: New fairing to give to your bike a new cafe racer look. (Coming Soon).

208917: Complete relocation kit that include: bracket, license plate holder, new shock absorber caps and EC approved led tail light.

209015: Dashboard plate for Harley Davidson XL Sportster 06 up fuel injection models. Utilises the original speedo, with new billet aluminium surround/bracket incorporating the original warning lights. This model replaces the original bracket for use with original handlebar risers. Supplied with full instructions and everything needed for installation.

801732: High Performance Bitubo rear shock absorber.
- Micrometric metal ring for spring preload.
- Rebound (continuous ring)
- Compression (clicking knob on top of separate tank)


The primary is open. Built originally for racing use with our Buell and due to the experience established, we made it also for this H-D Sportster 883. To mount it, we open completely the crankcase with purpose of seal the left case (close the bottom hole “primary-gearbox” plus the hole that hold the two shaft of the shifter forks), and make a hole to drain oil from gear box. Obviously we replace all original bearing with sealed one. It’s also necessary to replace with a sealed ball-bearing the original shifter drum bushing, while we do this we also replace the right bushing that will make the shift gear easier and smoother. With this modification, not only we reduce drastically inertial mass but we can also use a good quality oil on the gearbox without that it get ruined by the dust of the friction plate.

In collaboration with Civico 10, the Pordenone based shop, workshop and garage specialised in Milwaukee based company's bikes and twins, the engine has been increased to 90 inches (which means 1470 cm3). Surely, the Sportster gains some more hp, but the most important thing is that the sports behaviour is enhanced.

The rear has been risen with risers-block and absorbers by Bitubo, to get a cafe racer geometry.The rear fork is CNC machined worked part (still a prototype), specifically realised to host a 200 mm tyre. It is really a good looking at a glance. With this new swingarm, it was necessary to reduce the stress on belt transmission realign fulcrum, pinion and hub with a belt puller.
