Below is just a selection of the comments we receive from our customers:

 

Testimonial to the "Dual Power" system! (XT500, RMK-4): "(I) Just wanted to thank Marcus and his team for my TT/XT "Full Power Competition" RMK-4 ignition kit, and Kate for putting up with my email enquiries. 

This kit fits up very easily and comes with easy to read instructions. I had to remove the flywheel twice more after installation to reset the timing with the stator plate, before then finely tuning the timing using a strobe light and the adjuster on the black box. Easy. 

The difference over the old points ignition is immediately noticeable, not just because she's now easier to start! The motor's willingness to rev and the crispy response right through the rev range is certainly noticeable once in the saddle. My bike's power delivery used to taper off in the upper end of the rev range so I hardly ever bothered to go there - but now she keeps pulling cleanly all the way through. Thanks again. " Aug 2017.

XT500 RMK-4 "First test of the kit was 7 grueling laps of the TMCC Vinduro Sprint course (Australia) over the weekend - she performed flawlessly." Aug 2017

New TY175 Clubman-Pro electronic ignition kit "The 175 seems to run very well and the map switch does appear to make a real difference!" UK July 2017

 

"Thank you so much for taking the time and effort to call me in the US. 1. Thank you for following up on my order. 2. Thank you for letting me know there was a problem with my e mail. The problem was resolved with my provider, but if you had not taken the time to call me I may have been without service for a lot longer. You now have a loyal customer for life." June 2017

 
Kawasaki KH400 HT Ignition coils (HTC16) "Fitted 3 of your coils today, a nice experience, to have excellent pattern parts that fit perfectly & work. Well done everyone at Speed Shop." May 2017

Magneto rewind of a 200cc Rabbit Scooter: "Thanks to the capable team at Rexs-Speedshop my 1953 Fuji Heavy Industries Rabbit S48 scooter is once again pounding the streets of Tokyo. With rewound magneto and charging coils, a flick of the flywheel produces a spark at the plug you can HEAR and with an electronic regulator supplied by the Speedshop maintains battery charge even with a 35W halogen headlight fitted. Many thanks to the Speedshop team" March 2017

Suzuki GT500 source coil assembly (SC-2) "Super fast delivery, but even better the parts made my GT500 / TR 500 ´71 spec engine perform super, guess plus 3 to 5 HP in all range and immense  gas response, super start hot and cold and even cruising at low RPM is now possible" Sept 2016 Denmark

 

Flywheel magneto HT coil rewind &12 volt conversion: "You are amazing!!! Got the scooter to firing-up stage last night (200cc side valve single). A two-fingered flick on the rotor's cooling fins produces a spark you can actually hear! A delicate stroke on the kickstarter produces instant starting. AND it idles at just over 500rpm. Max. charge just over 4 amps. Break even with the 30 watt halogen headlight and LED taillight board is a shade over 1500rpm. All in all beyond my wildest expectations." Japan August 2016

TT500 Dual Power Ignition "My bike has a 540cc piston and a flat side carb.....I can't believe how easily it started when I fitted your ignition......When you're stuck in mud its good to know the bike will start easily......The idle was so stable - it just sat thumping away like a stationary engine! It never idled well on points ignition. I will let you know how the bike performs at the next Enduro race in Wales!" Oct 2015

XT500 12 volt conversion kit: "I just decided to buy a 12v conversion kit from Rex's Speed Shop, since my regulator needed replacing, and my 6v system was giving me trouble. 90 bucks and 20 minutes later I have a fully functioning 12v system. Speed Shop's used a battery eliminator since I've already lost enough paint due to battery acid spilling. The kit was easy to install and works just fine.

XT500/TT500 electronic ignition kit "Just fitted my kit today and I am super impressed! Starting my bike used to be a ritual, it had to be done in a certain way, don't even look at the throttle, quarter choke when cold , get that exact sweet spot on the kick etc. and when it was hot it was a bastard! With the new kit it just starts no worries at all. The kit was basic to fit and the advance curve is so so much better." Sept 2014

"I have now dynoe'd the Saltie at Cafe Racer...your CDI ran flawlessly up to well over 8,000...I am running it with the aftermarket coil I previously mentioned as well. Excellent result! Good piece of kit!" April 2011 Australia

"Works like a charm! Finally got a chance to wire up the bike.  Got spark!  Got it started.......given the temperature and altitude it's already starting easier than our other (stock) SR…..It was truly a pleasure working with you.  And I really appreciate your contributions to the forum (www.sr500forum.com) on this and other subjects."  December 2010 USA

"I got the CDI unit last Thursday! Great service! "July 2010 SR500 Owner USA.

"I've road tested the CDi I bought from you some months ago. Confirm what forum mates already said: found that starting is a lot improved; throttle response is, too. So far it's very good. 5 stars!" SR500 owner Italy June 2010

"Hi; Just wanted you to know that the CDI box I ordered for my 78 SR500 arrived quickly.  It is installed and I am very pleased with the results.......quicker starting and a noticable  increase in throttle response throughout the range.Thanks." SR 500 owner USA 10 May 2010

"Fitted the CDI to the (SR500) E Model engine and man what a difference. Right from start one could notice the improvement. I thought she was already easy to start, it is now even better. Idling is smoother and less prone to stall. Riding the bike is smoother all through the rev range. In top gear it pulls from low revs so much easier…...…I can not believe what a difference the unit has made. I am very suitably impressed…...….I had a aftermarket CDI and it was OK but did not perform as well as yours. One very happy little chappy" SR500 Rider Australia (purchased 2 units!)

"…….just got back from test ride, about 30 miles on my usual route, this gadget is definitely better on the pick-up from lowdown, can only describe it as a more 'crisper feel' and a bit more free revving. Starting is fine and possibly better than was. Not put the strobe on it but will do at some stage but no pinking evident and knowing the bike inside out I reckon she's running better than ever!”  SR Rider UK

“I pulled my other bike out with the proper (Yamaha) CDi on it and ran it with both the stock and your CDi and couldn't tell any difference except that with your box it started much easier”. SR Rider USA

“Rode the SR in a Classic Club ride today...tested out the new CDI at the same time...bike started normally and ran well throughout...all the way through to red-line at one stage…….A first class piece of kit.” SR Rider Australia

"Fast delivery,easy straight hook-up,works fine seems to help in the midrange in early testing.Highly recommend this product if you need a new CDI box.Cost is 1/3 Yamaha's price so excellent value..... even if you don't need one right away." SR Rider Canada

"Praise be to Aero! Fitted mine last week (on a 1981 motor) and it is definitely smoother through the lower range and whilst cruising (which is 99% of my riding commuting through traffic), very nice product, great service and of course, the right price!" SR Rider Australia

'Excellent! Fast delivery and excellent quality product.' USA Oct 2011

"Morning Marcus, just finished a 500 mile plus off road event in the Pine Barrens of New Jersey, to say it was wet is an understatement, water crossing 50 yards wide, many full throttle runs, loads of idling, bogs, sand, rain and cold morning starts, etc. The Speed Shop CDI performed without fault whatsoever!" Chris Grimm. May 2011

"Rex’s Speed Shop have a complete testing guide posted on here (SR500 Forum & our website site….Rex) which gives all the resistances that should be between the terminals etc.

This is a brilliant guide, is simple to understand and all you need is a basic multi-meter to complete the check. I’ve had problems with a couple of engines with this - especially if they have been sitting around a while. If you are not happy doing this yourself Rex will check it out and your CDI for a very reasonable cost (plus your postage cost !!!!!!!!!!!!!).  "12 Bore" SR 500 Forum April 2012

 "Well what can I say, The man worked wonders on my very sad looking stator plate i sent him, the service was excellent and he turned it around in a couple of weeks from door to door!
